An elementary school teacher want to know if she has the materials needed for the labs in a science book. She reads the materials list for every third experiment listed and finds that she does not have the materials needed for one of them. What is the sample in this situation?

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=
