Answer:
(0, -4)
Explanation:
The y-intercept is the point on the line where it crosses the y-axis. That point has x-coordinate equal to zero. To find the y-intercept, set x=0 in the equation and solve for y:
3y = -12
y = -12/3 = -4
The y-intercept is -4. The point coordinates are (0, -4).

You may notice that in the standard form equation, ...
ax +by = c
The x-intercept is c/a, and the y-intercept is c/b.
