The coordinates of 3 of the vertices of a parallelogram are (–3, 4), (–2, 1), and (2, 6). 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.)

anonymous · Answer

Since the lines are parallel you know the slope is gunna be the same as (-3,4)(-2,1) which is -3
you already have half of the equation: y=-3x+b
just plug in (2,6) in this equation to find b and your answer is y=-3x+12
