# Math Help - solving equations.

1. ## solving equations.

Any info on how to solve these would be greatly appreciated! I am in an online math course and it's been years since I've taken a math class so I'm having some trouble. Thanks!

1) Given 5x + 2y = 9, solve for y in terms of x. Then identify the slope of the line and the y-intercept of the line.

2) Solve the equation: 6x - 2y = 12 for y.

2) Solve the equation: 6x - 2y = 12 for y.

1) If the equation of a line is given in $y = mx + c$ form, then you can read off the slope ( $m$) and the $y$ intercept ( $c$)[/tex].

So $5x + 2y = 9$

$2y = -5x + 9$

$y = -\frac{5}{2}x + \frac{9}{2}$.

What is the slope and $y$ intercept?

2) $6x - 2y = 12$

$-2y = -6x + 12$

$y = 3x - 4$.
