Learning target I can find the distance between two points on the coordinate plane using absolute value, explain why the method works, and use it on a problem I have not seen before.

Remember7.6 Small Group · Group 2

Check the signs before you compute, because the same side of 0 means subtract absolute values and opposite sides means add them. Two negative coordinates are on the same side of 0, so you subtract their absolute values.
