Question

identify y intercept

4x + 9y = 144

Answer 1

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

Answer 2

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

Answer 3

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.

Answer 4

Do you get it now?

Answer 5

Yes, could you give me an answer?

Answer 6

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.

Answer 7

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

Answer 8

0,16?

Answer 9

Yep!

Thank you.
