WebThe second inequality is y is less than 2x minus 5. So if we were to graph 2x minus 5, and something already might jump out at you that these two are parallel to each other. They have the same slope. So 2x minus 5, the y-intercept is negative 5. x is 0, y is negative 1, negative 2, negative 3, negative 4, negative 5. WebA closed interval notation is a way of representing a set of numbers that includes all the numbers in the interval between two given numbers. In this notation, the numbers at the endpoints of the interval are included in the set. The notation for a closed interval is typically of the form [a,b], where a and b are the endpoints of the interval.

Since the line graph for 2x - y = 4 does not go through the origin (0,0), check that point in the linear inequality. Step 2: … WebOct 6, 2024 · Step 1: Graph the boundary line. In this case, graph a dashed line y = − 3x + 1 because of the strict inequality. By inspection, we see that the slope is m = − 3 = − 3 1 = rise run and the y -intercept is (0, 1). Figure 3.8.7. Step 2: Test a point not on the boundary. A common test point is the origin (0, 0). pirjo piipponen polvijärvi
