Yes, if it were -2, it WOULD change the answer:
Y=mx+b.
Y=4x + b. (Plug in 4 for slope)
-2=4(3)+b (Plug in (3,-2) as -2 for y and 3 for x).
-2=12+b.
b=-14 (subtract 12 from both sides)
Now, plug in b, the y-intercept into the equation.
Y=4x-14

The easiest way to do this is to plug what you are given into
y = mx + b
and find b...like this...
2 = (4)(3) + b
2 = 12 + b
b = -10 and then
y = 4x - 10
