The points (2,1); (-2,-1); and (-1, -1/2) are on the graph.
Work Step by Step
In order to solve this problem, first find out which points are on the line. In order to do this, plug each point into the equation and see if the equation results in a true statement. Next, plot the points that do satisfy the equation on a graph. Finally, draw a straight line through all of these points. (The graph is attached.)
