Answer:

To graph the inequality y>3x−8, you can follow these steps:

1. Start with a grid or graph paper. Label the x-axis and y-axis.

2. Identify the y-intercept: To find the y-intercept, set x = 0 and solve for y:

y=3(0)−8

y=−8

So, the y-intercept is at point (0, -8).

3. Identify the slope: The slope of the line is the coefficient of x, which is 3 in this case.

4. Plot the y-intercept: Mark the point (0, -8) on your graph

5. Use the slope to find additional points: Since the slope is 3, it means that for every 1 unit you move to the right along the x-axis, you should move 3 units up along the y-axis. Similarly, for every 1 unit you move to the left along the x-axis, you should move 3 units down along the y-axis. Plot a few more points based on this slope.

If you move 1 unit to the right from (0, -8), you arrive at (1, -5).

If you move 1 unit to the left from (0, -8), you arrive at (-1, -11).

6. Draw a dashed line: Since the inequality is y> 3x-8, the line representing the boundary should be dashed. This indicates that the points on the line are not included in the solution.

7. Shade the region above the line: Since the inequality is y>3x-8, you want to shade the area above the dashed line. This means all the points in that shaded region satisfy the inequality.

Your graph should now show a dashed line with a shaded region above it, indicating the solution to the inequality y>3x -8
