Question

y=x-8 how would I do it

Answer 1

to find two points that satisfy the function, you need to give one value and calculate the other one, for example.

I will use x=4 and x=8

when x=4

y=4-8=-4

so one point is (4,-4)

and when x=8

y=8-8=0

so the other point is (8,0)

so you need to graph these points and then plot the line, like this:
