First you have to convert to slope-intercept form. y=mx+b. Do you know how to do that?

I dont. My choices are: 0,16 0,36 16,0 36,0

Okay. Basically, when you find a y-intercept, the x value is always going to equal 0. To find the y-intercept and only the y-intercept, you basically just solve 9y=144 like it's a one-step equation. Whatever answer you get is the y-value in the ordered pair.

Do you get it now?

Yes, could you give me an answer?

Ordered pairs are sorted as (x, y) and we know x=0 so (0, _) 9y=144, solve by isolating y. We do that by dividing 144 by 9. Whatever the quotient is is plugged into the ordered pair.

You should be able to get the answer yourself from there.
