Homework Help: Math-Linear Equations

Posted by Kate on Monday, January 16, 2012 at 4:27pm.

Please let me know if I understand this correctly.
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!!!!!!
