    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.

    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.

    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.
