Question

If M is the midpoint of AB, A(-3, 4) and M(-1, 2) find the coordinates
of B.

Answer 1

B(1,0)

Explanation:

The midpoint of (a,b) and (c,d) is ((a+c)/2,(c+d)/2)

Essentially, you just average the x and y values.

So, the average of -3 and b_x is -1.

The average of 4 and b_y is 2.

So x=1 and y=0
