represents the point

Graph this point and the point corresponding to

*in order to sketch the line.*

Use the format wherem = slope (growth) and

Find the growth and substitute one of the coordinates of a point in the problem and solve for b.

A line that is perpendicular to

*has a slope that is the negative reciprocal of the slope of the line*
