Best ResponseYou've already chosen the best response.03x + 4y >= 20 disregard the > sign at the moment. We need to find the x and y intercepts of this graph. To find the x intercept, we sub in 0 for y. 3x + 4(0) = 20 3x = 20 x = 20/3 (for the graph, it is (6 2/3,0)  that is 6 and 2/3 To find the y intercept we will go ahead and put the inequality in y = mx + b form. 3x + 4y >= 20 4y >= 3x + 20 y >= (3/4)x + 5 In y = mx + b form, the m stands for the slope and the b stands for the y intercept. So our slope is 3/4 and our y intercept is 5....for graphing purposes that is (0,5) So map your points (6 2/3,0) and (0,5).....connect the points with a solid line because of the equal sign in the problem. Also, the your points will be marked with a solid circle. And since y >= 3x + 5....the shading will occur above the line. If you want to use your slope (3/4), start at the y int (0,5) and and come down 3 spaces, then go right 4 spaces...keep doing this and your should land on the x int. It should look something like this...and all that scribble is where the shading is. dw:1441902439463:dw
