from y=x, you stretch the graph by 4, which gets you y=4x, so the graph is thinner, then move the graph y=4x down by 7 to get the desired equation

I would start at the yintercept (0, 7), because the form of the equation is y=mx + b, where b is the yintercept.

Now go up 4 units and to the right 1 unit because m = 4/1

Hmm. I see. So how would I solve the 4x  y = 7 I need to solve for y? Wouldn't I divide 4x by itself?

When you asked to solve FOR y, it means solve with reference to y; that is, get y all alone on one side of the equation.

Yup, so in the equation I need to get 4x off of the right side. How would I do that? Btw, this is part 2 of the question.

You don't "need to get 4x off of the right side" just get y alone on either side will do.

Both x and y are on the LEFTside 4x  y = 7
