Step 1
Multiply each side of the inequality by 4 to solve for x while keeping the inequality balanced:
4 × x 4 < 4 × 9 
4 × x 4 < 36 
x < 36 
We solve this by placing a vertical line on the x-axis at 36.

Because there is no "or equal to" phrase in the inequality, which is merely "less than," the line will be dashed.

Therefore the solution does not contain the point 36.
