Question

Solving for Y. Write the following equations in slope-intercept form.

1) 3x-2y= -16
2) 9x - 7y = -7
3) x - 3y = 6

Answer 1

1) 3x - 2y = -16 Subtract 3x from both sides
-2y = -3x - 16 Divide both sides by -2
y =
`(3)/(2)`x + 8

2) 9x - 7y = -7 Subtact 9x from both sides
-7y = -8x - 7 Divide both sides by -7
y =
`(8)/(7)` + 1

3) x - 3y = 6 Subtract x from both sides
-3y = -x + 6 Divide both sides by -3
y =
`(1)/(3)` - 2
