    Slope Intercept Form

    Hello everyone,

    I am having some troubles remembering the application of slope intercept form. The question is:

    Write the line in slope intercept form. Identify slope and y-intercept. Then graph.

    -2x + 3y=9
    I understand slope intercept form, but forget how to find slope and y-intercept.

    I think the y intercept is 3, but am completely blank on the slope.

    Thank you all very much

    -2x + 3y=9

    3y=9+2x

    y=\frac{2}{3}x + 3

    Y-intercept is three
    Slope is two thirds

    So, just to make sure I understand this, the next problem is 8x - y=2

    8x - y=2

    y = -2 - 8x

    Slope= -8
    Y int = -2

    correct?
