Question

Steph places a point on a coordinate plane at (3,-2). She wants to place another point across the x-axis, and it must be 7 units away. Where will Steph place the other point?

Answer 1

(10, -2) or (3, 5)

Explanation:

Two options are possible when maintaining either y or x co-ordinate.

When maintaining y co-ordinate

New x co-ordinate is 3+7=10

Point (10,-2)

While maintaining x co-ordinate

New y co-ordinate is -2+7=-5

Point (3,5)
