Question

given abc with a(-4,1), b(8,-1), and c(-2,9), write the equation of the line containing midsegment xz in standard form, where x is the midpoint of ab and z is the midpoint of bc.

Answer 1

hint:
1) use your midpoint formula to find X, and then the midpoint formula again to find z
2) Use those two points to find the slope of the slope of the new line
3) Use the slope and a point to find the equation of the new line.
