Question

If the parallel sides of a trapezoid contained by the lines y = -x + 5 and y = -x - 9, what equation represents the line contained by the mid-segment?
A. y = -x – 2
B. y = x + 2
C. y equals negative one-half x plus 7
D. y = -x + 7

Answer 1

ans: D slope is -1 (same as the lines given) and the y intercept will be in between 5 and 9, which is 7.

Answer 2

oh okay thank you :)
