Question

Find the midpoint of AB if A(-3, 8) and
B(-7,-6).

Answer 1

C(-5, 1)

Explanation:

Given:

• Points A(-3, 8) and B(-7,-6)

To find:

• Midpoint

Solution:

Let the midpoint be C(x,y), then:

• x = -3 - 1/2*(-3 - (-7)) = -3 - 1/2*4 = - 3 - 2 = -5
• y = 8 - 1/2*(8 - (-6)) = 8 - 1/2*14 = 8 - 7 = 1

So midpoint is C(-5, 1)
