Ok so the formula for point-slope is:
m=slope
y1 = y point that's given
x1 = x point that's given
The problem says "use the point (-1,-4)"
so we will put it into our equation.
(-1,-4)
-1 is our x, and -4 is our y, now we can put it into the equation.
Now we need to find the slope using:
y2=4
x2=3
y1=-4
x1=-1
m=2
So the answer is..
