# Calculating linear equations from planes

The points on a plane: A(-3;2) and B(1.5;-3) are included in a parallel right to another one which crosses point at P(-2;-4)

Find:

a) The equation of this last right

b) The equation of the right which passes through the origin and is perpendicular to both of them

#### Solution Preview

a) Given to points A(-3,2) and B(1.5,-3) we can find the slope

of the line (right) passing through them.

The slope is m = (-3-2)/(1.5-(-3)) = ...

#### Solution Summary
