x= -2, -1, 0, 1, 2

do these one at a time so like 4-(-2)=y (it doesnt really equal y i hope u know that sry) it actually = 2 but check that with a calclater

then 4-(-1)=y and so one dont do all the numbers for x at once

then solve the equation and once u get it solved that will be you y answer then you will get an orderd pair so then u graph it on a corrdinate plan

IMPROTANT: if ur instructions say plot the points just plot the points on the graph BUT if ur instrustions say plot the equation(s) then u plot the points a then put a very big line threw them with arrows at both ends.

make sure your line is straight too!!!

hope i helped
