First you have to find the y-intercept (which is 0 ) and mark a point on it. Then take the slope (which is 1/2 ) and apply it to the y-intercept. to plugin the slope to the graph you need to start at the y-intercept (0,0) , go up 1 unit and go right 2 units and then mark a point there , go up 1 unit more and go right 2 units and then mark another point there. After you mark more points in that same pattern (slope) you cross a line through the points.
