I'm trying to put this in y intercept form so I can graph it but it keeps coming out as a fraction for the slope nd y intercept...what am I doing wrong?

3y+12=4x+4

Leon A.

How do u put a fraction on a graph?

You can determine the size of the grid on your graph. Since the equation contains 3rds, make each line equal to 1/3.
The intercept 8/3 would be 8 lines up the y-axis.

The slope is just rise/run or 4/3 (3 to the right and 4 up).  You'd need to draw your y-axis such that each unit of 1 is divided by 3 (e.g., 0, 1/3, 2/3, 1, 4/3, 5/3, 2, etc.).
 
Does that help?

The y-intercept is 8/3.  You can then use the slope from there.

Sorry, y-intercept is (0, -8/3).
