Triangle PQR has vertices P(-3, -1), Q(-1, 7), and R(3, 3), and points A and B are midpoints of PQ and RQ, respectively. Use coordinate geometry to prove that AB is parallel to PR, and is half the length of PR.

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
