Question

Find the midpoint of CD if c= (9,2) d= (-7,-9)

Answer 1

To find the midpoint of a segment you need to use this equation:

(x1+x2/2, y1+y2/2) so if you plug in the numbers its...

9+(-7)/2, 2+(-9)/2

then solve to find x and y coordinate

x= 1 and y= -3.5

so the midpoint of CD is (1,-3.5)

Answer 2

1, -7/2 (if you need the answer as a fraction)
