The best way to answer this question is to ask yourself what the Y intercept is. The Y intercept is the point on the graph when the line crosses the Y axis. This point will always be wherever X is equal to 0.
So, to find the answer, we need to say that X = 0
3(0) - 2Y = 6
Zero times any number equals zero, so we are left with:
-2Y = 6
Now, we solve for Y by dividing both sides by -2.
Y = 6/(-2)
Y = -3
So, when X = 0, Y = -3.
Thus, the Y intercept is at point (0,-3).
