Question

Write an equation of the line shown in the graph in slope intercept form (y = mx + b). Show

your work for full credit.
(4,6)
(2, 2)

Answer 1

y = 2x - 2

Explanation:

Points on graph: (4,6) and (2, 2)

Slope:

m=(y2-y1)/(x2-x1)

m=(2-6)/(2-4)

m=(-4)/(-2)

m = 2

Slope-intercept:

y - y1 = m(x - x1)

y - 6 = 2(x - 4)

y - 6 = 2x - 8

y = 2x - 2
