USING SLOPE-INTERCEPT FORM.

highlight_green%28y=mx%2Bb%29, m is slope, b is y-intercept.
b=y-mx
Use the given point that the line must contain.
b=-9-%283%29%28-4%29
b=-9%2B12
b=3
Equation is highlight%28y=3x%2B3%29

USING POINT-SLOPE FORM.

Plainly using this form, y-%28-9%29=3%28x-%28-4%29%29
highlight%28y%2B9=3%28x%2B4%29%29;
or if you want to simplify and reach general form,
y=3%28x%2B4%29-9
y=3x%2B12-9
highlight%28y=3x%2B3%29
