I am having trouble with part c.

I think that what's being asked for is to compute the following multiplication, to start:

Once you get that multiplication, what do you suppose you should do next? - July 20th 2010, 07:01 AMStuck Man
I think it is done like parts a and b but there is much more work.

Well, show me how you did part b, for example, and what work you've done on part c.

Yes, c is done exactly like a and b. I think if you try to write both components after your multiplication as "Ax+ B", you will notice an easy relation between the two components.

I have chosen (x, mx+c) and (1, m+c). Maybe I should have chosen two specific x values?

My images and being displayed too large with IE6. They are ok with Firefox. How are they for you?

I've done far more work than is required. Only the top line is needed. y=mx+c maps to y=2x.
