๐ŸŸข Easy

1Which integer is greater: โˆ’4 or โˆ’9?

๐Ÿ’ก Hint
Think: On the number line, which of these two sits farther to the right?
Greater always means farther right on the number line, and โˆ’4 sits to the right of โˆ’9 (closer to 0). So โˆ’4 is greater. (Think temperature: โˆ’4ยฐ is warmer than โˆ’9ยฐ.) Answer: โˆ’4

2What is the opposite of 7?

๐Ÿ’ก Hint
Think: Same distance from 0, but on the other side โ€” which sign does that give?
An opposite keeps the same distance from 0 but flips to the other side, which means flipping the sign. The opposite of 7 is โˆ’7.

3Evaluate the absolute value: |โˆ’6|

๐Ÿ’ก Hint
Think: How many units is โˆ’6 from 0 โ€” and can a distance ever be negative?
Absolute value is the distance from 0, and distance ignores direction (the sign). From โˆ’6 to 0 is 6 units, so |โˆ’6| = 6.

4Put these in order from least to greatest: 5, โˆ’2, 0, โˆ’8
Write them separated by commas.

๐Ÿ’ก Hint
Think: Reading the number line left to right, which end holds the smallest value?
Least to greatest is just left-to-right order on the number line, and the smallest sits farthest left. Order: โˆ’8, โˆ’2, 0, 5.

5Which quadrant contains the point (3, 5)?

๐Ÿ’ก Hint
Think: Positive x sends you which way, and positive y sends you which way? Where do they meet?
Positive x means right and positive y means up, so (+, +) lands in the top-right region: Quadrant I.

6What is the opposite of โˆ’12?

๐Ÿ’ก Hint
Think: Flip to the other side of 0 โ€” does a negative's opposite come out positive or negative?
Taking the opposite flips the sign across 0, so the opposite of a negative is positive. The opposite of โˆ’12 is 12.

๐ŸŸก Medium

1Fill the blank with < or >:   โˆ’3 ____ โˆ’10

๐Ÿ’ก Hint
Think: Which number is farther right on the line โ€” that one is the greater, so it gets the open end of the symbol.
Greater means farther right, and โˆ’3 sits to the right of โˆ’10 (closer to 0). The > symbol opens toward the larger value, so โˆ’3 > โˆ’10.

2Which number has the greater absolute value: โˆ’8 or 5?

๐Ÿ’ก Hint
Think: Strip the signs and ask which distance from 0 is bigger.
Absolute value is distance from 0, so the sign doesn't matter โ€” only size does. |โˆ’8| = 8 and |5| = 5, and 8 > 5, so โˆ’8 has the greater absolute value. (Even though โˆ’8 itself is the smaller number!)

3Reflect the point (4, 3) across the y-axis. What are the new coordinates?

๐Ÿ’ก Hint
Think: The y-axis is a vertical mirror โ€” flipping side to side changes which coordinate's sign?
The y-axis is vertical, so reflecting across it flips you left-to-right โ€” the x sign changes and y stays the same. (4, 3) โ†’ (โˆ’4, 3).

4Which quadrant contains the point (โˆ’6, 2)?

๐Ÿ’ก Hint
Think: Negative x sends you which way, positive y sends you which way? Where do those meet?
Negative x means left and positive y means up, so (โˆ’, +) lands in the top-left region: Quadrant II.

5Put these in order from least to greatest: โˆ’1, โˆ’9, 4, โˆ’4, 2
Separate with commas.

๐Ÿ’ก Hint
Think: Sort by position on the number line โ€” the most-negative number comes first.
Least to greatest is left-to-right on the number line, so the most negative goes first: โˆ’9, โˆ’4, โˆ’1, 2, 4.

6Starting at the origin, you move 5 left and then 3 down. Write the point as an ordered pair.

๐Ÿ’ก Hint
Think: Left and down each attach which sign โ€” and which value gets written first?
Left means negative x and down means negative y, and x is always written first. The point is (โˆ’5, โˆ’3) โ€” both negative, so Quadrant III.

๐Ÿ”ด Hard

1Find the distance between the points (2, 7) and (2, โˆ’4).
They share the same x-coordinate.

๐Ÿ’ก Hint
Think: Same x means a purely vertical move โ€” how far apart are the two y-values? Try |7 โˆ’ (โˆ’4)|.
When x is shared the points lie on one vertical line, so distance is just the gap between the y-values. Subtracting and taking absolute value handles the sign automatically: |7 โˆ’ (โˆ’4)| = |7 + 4| = 11 units.

2Reflect the point (โˆ’3, โˆ’5) across the x-axis. What are the new coordinates?

๐Ÿ’ก Hint
Think: The x-axis is a horizontal mirror โ€” flipping top to bottom changes which coordinate's sign?
The x-axis is horizontal, so reflecting across it flips you top-to-bottom โ€” the y sign changes and x stays. (โˆ’3, โˆ’5) โ†’ (โˆ’3, 5).

3True or False?   โˆ’40 > โˆ’25

๐Ÿ’ก Hint
Think: Is โˆ’40 farther left or right of โˆ’25 โ€” and which direction means greater?
Greater means farther right, but โˆ’40 is farther left (colder, deeper) than โˆ’25, so โˆ’40 is actually smaller. The statement is False โ€” the true one is โˆ’40 < โˆ’25.

4Which is greater: โˆ’|โˆ’8| or โˆ’5?

๐Ÿ’ก Hint
Think: Simplify โˆ’|โˆ’8| first (work inside the bars, then apply the outer minus) โ€” what plain number is that? Then compare on the line.
Work from the inside out: |โˆ’8| = 8, then the leading minus gives โˆ’|โˆ’8| = โˆ’8. Now compare โˆ’8 and โˆ’5 โ€” โˆ’5 is farther right, so โˆ’5 is greater.

5Find the distance between (โˆ’6, 4) and (9, 4).
They share the same y-coordinate.

๐Ÿ’ก Hint
Think: Same y means a purely horizontal move โ€” how far apart are the two x-values? Try |โˆ’6 โˆ’ 9|.
When y is shared the points lie on one horizontal line, so distance is just the gap between the x-values. The absolute value keeps the answer positive no matter the order: |โˆ’6 โˆ’ 9| = |โˆ’15| = 15 units.

6Point P = (โˆ’3, 6) is reflected across the y-axis, and that result is then reflected across the x-axis. Where does it land?

๐Ÿ’ก Hint
Think: Each reflection flips just one coordinate's sign โ€” apply them one at a time, in order.
Do the reflections in sequence. Across the y-axis flips x: (โˆ’3, 6) โ†’ (3, 6). Then across the x-axis flips y: (3, 6) โ†’ (3, โˆ’6). Two reflections, one for each axis, end up flipping both signs.
