Write an equation of the line in slope-intercept form that passes through (4,3) and is (a) parallel and (b) perpendicular to the line shown. the points on the graph are (1,6) (2,2)

Answer 1

(a)

Deteremine slope, m, between the two points.

Use the value of m in

m = (y - 3 / (x - 4)

(b)

Use the value -1 / m in

-1 / m = (y - 3 / (x - 4)
