    point-slope

    write an equation in point-slope form that has the same slope as -x+9y=12 and goes through point (-2,3)

    Hi Hatch,

    This would require you to know what the "point-slope" form of a linear equation looks like. I assume you know that from your studies.

    Point-Slope Form: [tex](y-y_1)=m(x-x_1)[/tex]

    You're going to have to find the slope of the graph of your given linear equation. Can you do that? Can you solve the equation for y to put it in slope-intercept form?

    If you can do all of the above, then you simply substitute the point coordinates you have for [tex]x_1[/tex] and [tex]y_1[/tex], and the slope you just found for [tex]m[/tex]

    Try it.
