    Start with y - y1 = m(x - x1) which is point slope form and plug in m = 6 (the slope) and (x1, y1) = (5, -1), which is the given point

    so would be y-1=6(x-5)?

    You have a -1 for your y so you have to subtract a negative number, which is adding a positive number.

    y-(-1)=6(x-5) and then simplify the left side.

    keep in mind that subtracting a negative is like adding ex: 2-(-3) = 2+3 11-(-7) = 11+7 x-(-z) = x+z

    ok so it would be y+5 correct?
