Which of the graphs below represents the equation 3x - 2y = -12?

No graphs shown but here is what I can tell you about it

3x-2y= -12
-2y= -3x-12
y= -3/-2x-12/-2
y= 3/2x+6

the graph will show a line, starting from bottom left and moving to the right, upwards. The line will cross the y-axis (vertical axis) at 6 above the x-axis. If you check the slope (which is 3/2) then you will find the line will also have a point at (2,9).

Hope this helps
