    How would I do this?

    \[y-y _{1} = m(x -x_{1})\] This is point slope form.

    find your slope (m) and plug in an x and y value to find your equation.

    So, -7 - (-6) = - 1/3 ( -5 - (-8)) ?

    Where did the 26 come from?

    point slope form means you don't solve for y, and gjhfdfg in point slope form you only plug in a single point, which is one X value and one Y value. so - \[(y + 7) = -1/3*(x+5)\] for the point (-5, -7)

    another right answer would be \[(y+6) = -1/3*(x+8) \] for the point (-6, -8) it doesn't matter what point you use, just that you use one. Hope this helps.

    the last one is for the point (-8, -6) but yeah sorry.
