Question

how do i graph x is less than or equal to 4, and y is greater than or equal to -8?

Answer 1

x <= 4
This graph would be a vertical line that crossed the x-axis at 4. Less than would refer to the left side of that line so that side of the graph would be shaded

y >= -8
This graph would be a horizontal line that crossed the y-axis at -8. Greater than would refer to everything above the line so that is where it would be shaded.
