Find the y-intercept. 3x – 2y = 15

Where does the Y intercept occur?

Solve the equation for y and then set x=0.

Hey galactus. I was trying to get the poster to think a bit. Instead of providing direct answers which you didn't, we can teach a bit.

If the poster doesn't know, he can say that. Then ask him to draw a line on a piece of graph paper through the y axis, but not through zero and ask about it.

Receipies aren't necessarily good.
