I have gotten to this point in the equation. My teacher says I have to solve for X and then graph that and that is what I am having trouble with.

It's not as usual to solve for x and graph it but what's the problem? Is the algebra tripping you up?

I can't graph 4/3, it has to be a whole number so my teacher told me to solve for x instead. When I try to solve for x my answers come out wrong. Could you show me the problem worked out step by step so I can see where I am messing up.

I graphed it as -3y on the grid, 4/1 as the slope and then graphed -1 on the grid and 2/1 as the slope. The intersect point was 1,1 but it was wrong. (Headbang)

I am still being told that my answer is incorrect even with y-int is 4/3 and the slope is -1/3. I have no idea what I am doing wrong. Thank you so much for all your help though.

It is the 4/3 that keeps stumping me. I have had no trouble being able to get a correct answer on any of my other problems but all my problems that have a fracture in them I cannot get the answer. I don't know how to plot the 4/3.

It is a computer program.

I don't know what to tell you. I've double checked my work and I'm pretty sure I have the right answer. Maybe look in a guide online? Or call a friend who might know how to input fractions.

Thanks for spending so much time trying to help.
