Question

or
Solve the inequality and graph the solution.
2q+1>9
To draw a ray, plot an endpoint and select an arrow. Select an endpoint to change it from closed to open. Select the middle of the ray to delete it.

Answer 1

Solve:
2q + 1 > 9
2q > 8 (subtract 1)
q > 4 (divide by 2)

Solution: q > 4. In interval notation: (4, ∞).

Graph: put an open circle at 4 and draw a ray to the right (arrow pointing right) to indicate all numbers greater than 4. If using the ray tool: place the endpoint at 4, click the endpoint to make it open, and select the arrow pointing right.
