Transcript

This problem wants us to figure out which graph represents the inequality, negative 2 x, plus 3 y greater than 12, and to start figuring out, which graph is correct. We’Re going to get this inequality in a slope, intercept form so we’ll add 2 x over to give us 3 y greater than 2 x plus 12 and then we’ll divide by 3 to isolate y and that’s going to give us y greater than 2 thirds x. Plus 4 point, so this is the inequality. We’Re trying to graph, and sometimes looking at your intercept, will help you to eliminate some choices. But it looks like all 4 of our options are going through the correct y intercept of 4 and they’re all also using our slope correctly, to make more points where we go up to over 3 a few times. We can also go down to left 3 to make a few points. The way we’re going to decide which inequality is the right graph is by looking at 2 things first, when we don’t have an equal to inequality and that’s greater than or equal to or less an…
