Question

solve the inequality and graph the solution.
2 > \frac{a}{2}
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: Multiply both sides by 2

$2\times2>\frac{a}{2}\times2$

Step2: Simplify the inequality

$4 > a$ or $a<4$

Answer:

The solution of the inequality is $a < 4$. On the number - line, we use an open circle at $a = 4$ (since $a$ cannot equal 4) and draw a ray to the left to represent all the values of $a$ that satisfy the inequality.
