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?
2 answers:
The possible coordinates of point A is (-1,-1)
Answer:
(-1, -1)
Step-by-step 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)
