Can anyone help me with do these few math questions, I'm pretty noob at math.

What are you having trouble to understand?
I think it will be good for you if you could tell us your problem then we'll try to explain rather than telling you the answer right away.

I know how to do the equation, but I don't understand how I can turn that into a graph.

F represents the y axis.. the other side of the equal sign will represent the X result..

For every value of C, there will be a value for F..

Plot C vs F and you get your graph.

Looks like:
Should be the reverse of that though.. because your plotting Celsius on the X axis instead of the Y axis like the graph above..

5F = 9C + 32*5

5F - 160 = 9C
C = (5F - 160)/5
C = F - 32
Set C to 0…
0 = F - 32
When F = 32, C will be 0.. when F < 32 C will be less than 32..

Thanks that helped. The only thing now that I'm not sure about is question 3.

5F - 160 = 9C
C = (5F - 160)/5

You divided one side by 5 and the other by 9 :P

And it could be done easier:
F = 9 * c / 5 + 32
c = 0
F = 9 * 0 / 5 + 32
F = 32
