Linear Inequalities Graphing and Application

Randy must graph x + 3y > 6. Part of his effort is shown in the graph. Which of the following is true about Randy's work so far?

• All is great so far. He just needs to do the shading part.

• He has the incorrect y-intercept indicated since it should be at (0, 6).

• His "rise over run" technique is incorrect since it is reversed.
