Question

solve the inequality and graph the solution.
4q < 8
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: Isolate the variable q

Divide both sides of $4q < 8$ by 4. So $q<\frac{8}{4}$.

Step2: Simplify the right - hand side

$\frac{8}{4}=2$, so $q < 2$.

Answer:

The solution of the inequality is $q < 2$. On the number - line, we plot an open circle at 2 (since the inequality is strict, $q$ cannot equal 2) and draw an arrow to the left to represent all the values of $q$ that satisfy the inequality.
