Slope-Intercept and Point-Slope Review!

Slope-Intercept Form

100

Write an equation in slope intercept form.

Slope = 4

y-intercept = -7

y = 4x - 7

200

Write an equation in slope intercept form.

Slope = 1/8

y-intercept = 24

y = 1/8x + 24

300

Write an equation in slope intercept form.

Line has a slope of 0 and passes through; (8,-5)

y = -5

400

Write an equation in slope intercept form.

(-5,2) and (0,12)

y = 2x + 12

500

Write an equation in slope intercept form.

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

y = 2x - 2

Point Slope Form

100

Write an equation in point slope form.

Slope = -3

Point = (9,2)

y-2=-3(x-9)

200

Write an equation in point slope form.

Slope = 8

Point = (-6,2)

y-2=8(x+6)

300

Write an equation in point slope form.

(9,7) and (4,5)

y - 7 = 2/5 (x - 9) 

 or      

y - 5 = 2/5(x - 4)

400

Write an equation in point slope form.

(-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

(-4, 6)

What's my slope?

100

500

(-9,-7) and (7,-4)

3/16

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

Write an equation in Point-Slope form that passes through: (4, -4) and (9, 1)

Then write the equation in Slope-Intercept Form.

y = x - 8

500

Write an equation in Point-Slope form that passes through: (-3, 10) and (1, 2)

Then write the equation in Slope-Intercept Form.

y = -2x + 4
