Question

Which of the following points has coordinates that are 5 horizontal units from point A?

A. left parenthesis 3 comma 2 right parenthesis
B. left parenthesis 3 comma 7 right parenthesis
C. left parenthesis negative 2 comma 7 right parenthesis
D. left parenthesis 5 comma 2 right parenthesis

Answer 1

A. left parenthesis 3 comma 2 right parenthesis

Explanation:

The point A is at (-2, 2) which is 2 units to the left and 2 units up from zero

We want 5 horizontal units from A. Horizontal means left and right

If we go 5 units to the right

(-2 +5 , 2) = (3,2)

If we go 5 units to the left

(-2 -5 , 2) = (-7,2)
