## Amenah8 one year ago How would you solve 3x-2y=12 using slope intercept form.

1. pooja195

we need to isolate y right? so we need to subtract 3x from both sides now we have $\huge~\rm-2y=-3x+12$ any cles on what the next step is?

2. Amenah8

the next step is to divide the left side by -2.

3. pooja195

yes can you please do that? :)

4. Amenah8

I got -2y/-2 = 12-3x/-2 and then y = -6 -3x/-2 and the final answer is y = -6 - 3x/2. Is this correct?

5. pooja195

-6? where did that come from?

6. Amenah8

I got -6 by doing 12/-2.

7. pooja195

$\huge~\rm~\frac{ −2y=−3x+12 }{ -2y=-2y-2y}$

8. Amenah8

I did that except I didn't have it divided by -2y, I had -2 without the y.

9. texaschic101

keep in mind, when dividing by 2 negatives, the result is positive

10. pooja195

y=-3/2x-6

11. Amenah8

Ah, so that means that the answer would be a positive -6+3x/2.

12. pooja195

so yes :) good job! :)

13. texaschic101

y = 3/2x - 6

14. texaschic101

it need to be in y = mx + b form

Alright, thanks you two!

17. texaschic101

it is not -3/2....it is 3/2

18. Amenah8

Right.
