What do you need to know? Please get started. I'd suggest you graph the line y=1-3x first. Slope is -3 and y-intercept is 1. After you've done that, choose a test point not on this line, take its coordinates and subst. them into the inequality y=1-3x. Is the inequality then true? If yes, shade the area of the graph on the same side as that point. If no, shade the other side of the line.

i don't know how to graph it

OpenStudy (mathmale):

As I've told you, JJ, the slope is -3 and the y-intercept is 1. In other words, the y-intercept is the point (0,1). Like it or not, you MUST know how to graph straight lines. Open the Draw utility. Draw your 2 coordinate axes: x-axis and y-axis. Plot the y-intercept, which is the point (0,1). Do that now, please.
