Find the slope and the y-intercept of each equation:

1)y-9x= 1/2

+9x= 1/2 + 9x

y= 1/2 + 9x

slope:9; y-intercept: 1/2

2)2y-6=3x

+6 +6

2y=3x + 6

- -

2 2

so then: y=3x+3

3) -2y=6(5-3x)

-2y= 30-18x

- --

-2 -2

so then: y=-15-18x

(slope: -18; y-intercept: -15)

Thank you!!!!!!

**Steve**, Monday, January 16, 2012 at 4:33pm1) correct, but the usual form is y=mx+b, so you'd have y=9x + 1/2

2) you forgot do divide 3x by 2. y = 3/2 x + 3

3)You're getting things mixed up. Don't try to rearrange things in your head.

-2y = 30 - 18x

-2y = -18x + 30

y = 9x - 15
