Question

Write the equation for the following relation. Include all of your work in your final answer. Submit your solution.

P = {(x, y): (1, 0), (2, 4), (3, 8), (4, 12), . . .}

Answer 1

I already know the answer. I just need the steps to do it. (As in first we take blah blah blah then do this to get this then do that to get this.)

Answer 2

The basic outline is this

step 1) pick any two points you want

step 2) identify the coordinates and subtract the coordinates

step 3) divide the differences in step 2 (change in y over change in x). This gives the slope m

step 4) use the slope m from step 3, and any one of the points for (x,y). Plug these into y = mx+b and solve for b
