Question

solve the inequality and graph the solution.
0 > \frac{u}{-1}
plot the endpoints. select an endpoint to change it from closed to open. select the middle of the segment, ray, or line to delete it.

Explanation:

Step1: Simplify the inequality

Given $0>\frac{u}{- 1}$. Multiply both sides by -1. When multiplying an inequality by a negative number, the direction of the inequality sign changes. So we get $0 < u$.

Answer:

The solution of the inequality is $u>0$. On the number - line, we use an open - circle at $u = 0$ and draw a ray to the right.
