13 less than twice a number is at least -4

Question

Translate to an inequality then solve, and then graph.

Answer 1

If the number is x, then 2x-13≥-4.

2x≥9 adding 13 to each side, x≥9/2

The orange hatched area is the region covered by the inequality, extending outside the boundary of the picture. In other words the whole area to the right of the slanted line y=2x-13 and above the horizontal line y=-4.
