Question

Graph x ≤ 4, and y≥ -8.

Answer 1

Line with a formula of x = a is a vertical line while a line with a formula of y = b is a horizontal line on the other hand. In this case, the graph of x ≤ 4 is the region to the left of the line x  = 4 to negative infinity. The graph of y≥ -8 is the region above the line y = -8  to positive infinity.

Answer 2

The graph of x ≤ 4 is a solid vertical passing through the point x = 4 with the portion to the left of the line shaded.
The graph of y ≥ -8 is a solid horizontal line passing through the point y = -8 with the portion  above the line shaded.
