3x-2y=6
-2y=6-3x
y=3x/2-3
slope is 3/2
3x-y=-15
-y=-3x-15
y=3x+15
slope is 3

To find the slope in these problems, first solve for y. Then, the slope is the number that is in front of the x.
3x-2y=6 becomes y = (3/2)x - 3 ... slope is 3/2
3x-y=15 becomes y = 3x -15 .... slope is 3

The equation you have is in what is called "Standard Form," but you want the slope so you should rearrange it in "Slope Intercept Form."
3x-2y=6 // standard form
-2y=-3x-6 // pull out the neg form all
2y = 3x + 6 // Slope Intercept Form
y= 3/2x + 3
slope = 3/2
y intercept : (0,3)

-2y=6-3x
y=-3+3/2x
slope=3/2
-y=-15-3x
y=15+3x
slope=3
