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
