Write in point slope

100

(2, -5) m = -1

y + 5 = -1( x - 2 )

200

(2, 6) m = 3

y - 6 = 3( x - 2)

300

( 0 , 6 ) m = 1/2

y - 6 = (1/2) (x - 0)

400

(- 4, -7 ) m = -6

y + 7 = -6( x + 4 )

500

y intercept is -5   slope is 2

y + 5 = 2 ( x - 0)

Write in slope intercept form

100

x - y = 1

y = x-1

200

2x - y = 4

y = 2x - 4

300

x - 4y = -8

y = (1/4)x + 2

400

x + y = 0

y = -x + 0

500

3x + y = -5

y = -3x - 5

Write the Slope-Int. Form

100

through (4,-1), slope = (-1/2)

y = (-1/2)x + 1

200

through: (3,3), slope = (-1/3)

y = (-1/3)x + 4

300

through: (2,5), slope = 3

y = 3x - 1

400

through: (2,0), slope = (-3/2)

y = (-3/2)x + 3

500

through: (3, -5), slope = 9

y = 9x - 32

Given point slope write in slope intercept form

100

0 = x - 4

x = 4

200

y - 2 = -5(x+1)

y = -5x - 3

300

y + 4 = -(x+1)

y = -x - 5

400

y + 5 = -2(x-1)

y = -2x - 3

500

DAILY DOUBLE!!! y - 4 = (5/2)(x - 2)

y = (5/2)x - 1
