Question

Whicg graph represents the solution set for the inequality 1/2x <18

Answer 1

4th option

Explanation:

Took it on edge, or the graph that has 36 as a point and going left.

Answer 2

To draw the region that represents the solution of the inequality you have to:

1. draw dashed vertical line
`(1)/(2)x=18\Rightarrow x=36` (dashed because of sign of inequality is <, doesn't include notion equal to);

2. shade the region that determines all points on the coordinate plane that have x-coordinate less than 36.

The attached diagram represents the solution set for the given inequality.
