Slope Intercept Form Review!

Slope-Intercept Form

100

Slope = 4

y-intercept = -7

y=4x-7

200

Slope = 1/8

y-intercept = 24

y=1/8x+24

300

Line passes through; (1,12) and (0,9)

y=3x+9

400

Line passes through; (0,-7) and (8,-5)

y=1/4x-7

500

(0,-2) and (3,4)

y=2x-2

Point Slope Form

100

Slope = -3

Point = (9,2)

y-2=-3(x-9)

200

Slope = 8

Point = (6,2)

y-2=8(x-6)

300

(9,7) and (4,5)

y - 7 = 2/5 (x-9)  or      y - 5 = 2/5(x - 4)

400

(-2,7) and (3,-5)

y - 7=-12/5(x + 2)   or   y + 5 = -12/5(x - 3)

500

Identify a point on the line and the slope of the line in the equation           y - 6 = 2(x + 4)

m = 2

Point-Slope form to Slope-Intercept Form

100

y-2=8(x-3)

y=8x-22

200

y+17=-3(x-1)

y=-3x-14

300

y-11=1/5(x-5)

y=1/5x+10

400

y+2=1/6(x-3)

y=1/6x-2.5

500

Write an equation in slope-intercept form: (-3, 10) and (1, 2)

y = -2x + 4
