Learning target With my small group, I can find the distance between two points on the coordinate plane using absolute value — one step at a time, with support.
Remember7.6 Small Group · Group 1
Add the absolute values when the points are on opposite sides of 0, and subtract them when the points are on the same side. When two points share an x or a y, use absolute values to find the distance between them.

1Complete each step, then write the final answer.
Find the distance between (−6, 1) and (2, 1).
Show your workHint The y-values are the same. −6 and 2 are on opposite sides of 0, so add |−6| and |2|.
Final answer: -
2Complete each step, then write the final answer.
Find the distance between (−5, 3) and (4, 3).
Show your workHint Find the coordinate that is the same. Then look at the signs.
Final answer: -
3Complete each step, then write the final answer.
In a video game, a player stands at (4, −3). A coin is at (4, 5). How many units must the player move to reach the coin?
Show your workHint The player moves straight up. Is 0 between −3 and 5?
Final answer: -
4Complete each step, then write the final answer.
Point A is at (−3, 2). Point B is on the same horizontal line, 9 units to the right of A. What is the x-coordinate of B?
Show your workHint It takes 3 units to get from A to the y-axis. How many units are left?
Final answer:
Explain your thinkingHow do you decide to add or subtract the distances from 0? Use Leo's mistake to explain.
