3x + 15 = y
Cuts y axis when x = 0 ie at y = 15 (intercept)

Both C and D work.

3(-5)-0=-15
-15=-15

and

3(0)-15=-15
-15=-15

We need to put the equation in point-slope form.
y = mx + b where b is the y intercept
3x - y = -15
y = 3x + 15

The y intercept is where the line crosses the y axis, so the x value will be 0, so the point is D) (0,15)

3x-y = -15
Y = -15-3x
Y = 0 >>> -15-3x = 0
-3x = 15
x = 15/-3
x = -5

the answer is A
