So since I dont want to give you the answer im going to show you how to do it this way you learn for later problems.

For this one, they give you a point (x1, y1) and a slope m, and have you plug it into this formula: y – y1 = m(x – x1)
So here is a question involving the point slope formula (got it online):
    " Find the equation of the straight line that has slope m = 4 and passes through
     the point (–1, –6)."

The question has given you m = 4, x1 = –1, and  y1 = –6.  I'll plug these values into the point-slope form, and solve for "y=":

y – y1 = m(x – x1)
y – (–6) = (4)(x – (–1))
y + 6 = 4(x + 1)
y + 6 = 4x + 4
y = 4x + 4 – 6

y = 4x – 2 

So basically do the same thing here but plug in your numbers! (sorry for long answer)
