Answer 4

solutions*

Answer 5

Ok solve for y.

Answer 6

What do you get?

Answer 7

You can treat this like an inequality

Answer 8

When solving for y

Answer 9

can you plug in zero for the x value to solve for y?

Answer 10

No.

Answer 11

That is a mistake I have seen a person make before

Answer 12

What you need to do is make the equation become y > ______

Answer 13

So let me help with you this part
You have: 3x+2y>-7

Move 3x over
3x - 3x + 2y > -7 - 3x

Divide both sides by 2. Because we are not dividing by a NEGATIVE value, the inequality sign will not switch

2y/2 > (-7 - 3x)/2
y > (-7-3x)/2

Answer 14

Get it so far? I got the inequality in the form y > ______

Answer 15

Now, suppose the equation was:


y = (-7-3x)/2
