Slope Intercept Form

100

Write the equation for Slope Intercept Form.

y = mx + b

200

Write the equation for slope?

m = y_{2 -} y₁ / x₂ - x₁

300

m = 4; b = 2

y = 4x + 2

400

(7,1) ; m = 8

y = 8x - 55

500

(2, 5) ; m = -2

y = -2x + 9

Point Slope Form

100

(-6, -3); m = -1

y + 3 = -1(x + 6)

200

(-7, 6); m = 2

y - 6 = 2 (x+7)

300

(-2, 11);  m = 4

y - 11 = 4(x+2)

400

(0, -1) (5, 1)

y + 1 = 2/5 (x - 0)

y - 1 = 2/5 (x - 5)

500

(-2, 3); (0, -5)

y - 3 = -4 (x+2) 

y + 5 = -4 (x - 0)

Convert To Standard Form

100

4y = -2x + 5

2x + 4y = 5

200

y = 2x + 3

2x – y = –3

300

y = 3x + 5

3x – y = –5

400

y – 5 = 3/2 (x + 4)

3x – 2y = −22

500

y + 2 = −3/4 (x + 1)

3x + 4y = –11

2 Points to Slope Intercept Form

100

(9, -2), (4,3)

y = -x + 7

200

(-2, 5), (5, -2)

y = -x + 3

300

 (-5, 3), (0, -7)

y = -2x - 7

400

(3, 5), (2, -2)

y = 7x - 16

500

(-1, -3), (-2, 3)

y = -6x - 9

Rewrite In Slope Intercept Form

100

y + 2 = 4(x + 2)

y = 4x + 6

200

y + 1 = -7(x + 1)

y = -7x - 8

300

y - 3 = -5 (x + 12)

y = -5x - 57

400

y – 5 = 3/2 (x + 4)

y = 3/2x + 11

500

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

y = 1/2x + 5
