Answer:
(-1, 5)
(-1, -3)
Step-by-step explanation:
Given that coordinates of point B = (2,1) this means, x2 = 2 & y2 = 1.
The x coordinate of point A = -1
D = 5 units
Let's use the equation for distance between points, it is expressed as:
Solving further, let's square both sides,

Solving further, we have:

For the possible values, we have:


Therefore, the possible coordinates of point A are:
(-1, 5)
(-1, -3)
