Question

find the slope of a line that passes through the following points. (4,5) and (3,0) using the perpendicular and parallel slopes write slope intercept form equations for both perpendicular and parallel lines all perpendicular lines pass through the point(2,5) and parallel lines (-3,2)

Answer 1

find the slope m of the line joining the two points.

All parallel lines have the same slope m

All perp. lines have slope -1/m
