Question

Point B has coordinates ​(3​,2​). The​ x-coordinate of point A is -1. The distance between point A and point B is 5 units. What are the possible coordinates of point​ A?

Answer 1

The possible coordinates of point A is (-1,-1)

Answer 2

(-1, -1)

Explanation:

A (-1,y) & B (3,2)

the distance between A and B =

√(3+1)²+(2-y)² = 5

(3+1)² + (2-y)² = 5²

4²+ (2-y)²=25

(2-y)²= 25-16

(2-y)²= 9

2-y=3

y = -1

point A (-1,-1)
