Question

The coordinates of 3 of the vertices of a parallelogram are (–7, 3), (–6, 1), and (–4, 5). What is the equation for the line containing the side opposite the side containing the first two vertices? (Remember, opposite sides of a parallelogram are parallel.)

Answer 1

use the first two vertices (points) to get a slope, then use that slope and the third point to get the equation of the line you need.

Answer 2

thanks
