Write the slope intercept

9x + 2y = 3

Slope-intercept form is y=mx+b, so 1st thing you have to do is isolate the y variable. To do that, you would subtract 9x from both sides:

9x+2y=3

-9x - 9x

2y=3-9x

We have y on one side, but the 2 is still in front of it. So now you have to divide the whole equation by 2

2y=3-9x y=mx+b

- - - ➡️y = (3/2) - (9/2) x

2 2

Since we now have the b and mx mixed up, all you have to do is switch them

y = (3/2) - (9/2) x

y=-9/2x+3/2
