Please let me know if I understand this correctly.
Find the slope and the y-intercept of each equation:
+9x= 1/2 + 9x
y= 1/2 + 9x
slope:9; y-intercept: 1/2
2y=3x + 6
so then: y=3x+3
so then: y=-15-18x
(slope: -18; y-intercept: -15)
1) 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
Thank you so much - that clears it up for me!!! It's just been awhile since I've done this.
