Answer:

Explanation:

Please be sure to include the directions when you post a question. I will assume you want to graph this inequality 2x - y ≤ 5.

2x - y = 5 is a linear function whose graph is that of a straight line. Because of the ≤ sign, the solution set includes all points on this straight line PLUS all points below it.

x - intercept: Set y = 0 in 2x - y = 5 and solve the resulting equation for x:

2x - 0 = 5. Then x = 5/2, and the x-intercept is (5/2, 0).

y-intercept: Set x = 0 and solve for y: 2(0) - y = 5: y = -5. Then the y-intercept is (0, -5).

Plot both points (5/2, 0) and (0, -5). Draw a solid line through them. Shade the area BELOW this line.
