That is enough information for two points. The x-intercept given means one point is (15/4, 0).

Slope is m=%280-%28-3%29%29%2F%2815%2F4-3%29=3%2F%2815%2F4-12%2F4%29=3%2F%283%2F4%29=4.

Try point-slope equation form:
Using point (3,-3),
y-%28-3%29=4%28x-3%29
y%2B3=4x-12
y=4x-12-3
highlight%28y=4x-15%29 expressed in slope-intercept form.
