All you have to do is to reverse the order of the x and y components of (7,2):
(2,7).

Answer:

(2,7)

Step-by-step explanation:

Here is an example just to show that it works.

3x+2y=25

3(7) + 2(2) = 21 + 4 = 25

3y+2x=25

25-2x=3y

25/3 - 2/3x = y

25/3 -2*2/3=25-4/3=21/3=7

2x - 3y > -12. Rewrite the inequality so that y is isolated

Answer:

y < 2/3x + 4

Step-by-step explanation:

Hi there! So first, we need to subtract 2x from both sides:

-3y > -2x - 12

Now, we need to divide both sides by -3 to isolate y. Since we are dividing by a negative value, our inequality symbol will be flipped from > to <.

Your final answer is:

y < 2/3x + 4
