Substitute x-values into x. e.g. y>-3.5x + 2 let x be 1... thus, y>-3.5(1) + 2 y> -1.5 or y<1.5 another e.g. let x be 2. y> -3.5(2) + 2 y> -4.4 or y<4.4 And so forth. pluck in these coordinates into you graph and sketch a line through the points. NOTE: < in my explanation is equivalent to less than or equal to. same goes to >… greater than or equal to.
