Answer:
y = 2/3x - 7
Explanation:
First we must turn 3x + 2y = 6 to slope intercept form. In order to do this first subtract 3x on both sides of the equal sign, so we can get 2y by its self. Now we're left with 2y = -3x + 6 .
Next divide 2 from both sides to get y by its self. Now you got y = -3/2x + 3 (since 6 can be divided by 2 it's a 3 now) <u>Look above to see y= -3/2x +3 graphed</u>. ⤴⤴⤴
To find out the other equation we first need to know what its y-intercept is, and luckily for us we've already been given -3.

This is a bit lengthy, but I hope you get it :)
