What are the coordinates of point A?

Enter your answer as an ordered pair, formatted like this: (42, 53)

Answer 1

(x1+x2)/2 = Midpoint of x

(y1+y2)/2 = Midpoint of y

Plugging in the values you know:

(-5+x)/2=-3 Multiply both sides by 2

2(-5+x)/2=2(-3) Distribute and simplify

-5+x=-6 Add 5 to both sides

-5+x+5=-6+5 Simplify

x=-1

(1+y)/2=3 Multiply both sides by 2

2(1+y)/2=2(3) Distribute and simplify

1+y=6 Subtract 1 from both sides

1+y-1=6-1 Simplify

y=5

(-1,5) is the other end
