Objective 1●Check at least two points on the boundary of the graph to seewhether their coordinates satisfy the equation y 2 x 1.3Choose points with coordinates that are easily read from thegraph. In this case, choose the points (3, 1) and (6, 3).Substitute these values into the equation y 2 x 1 and3determine whether the equation is true.P o i n t ( 3 , 1 ) P o i n t ( 6 , 3 ) y 2 3 x 1 y 2 3 x 1Do you seethat . . .1 2 3 (3) 1 3 2 3 (6) 11 2 1 3 4 11 1 3 3The line is the correct boundary. It is dotted because theinequality y 2 x 1 does not include the points on the line3y 2 x 1.3●Check at least one point within the shaded region to be certainthe correct side of the line has been shaded. You can use thepoint (6, 0).P o i n t ( 6 , 0 ) y ? 2 3 x 10 ? 2 3 (6) 10 4 1The shaded area is on the same side of the line as (6, 0).The graph does represent the inequality y 2 x 1.322
