Question

R≤−9 write an inequalties on number line

Answer 1

Explanation:

You would draw a continuous number line, with numbers -10,-9, -8. Because of ≤, you draw a filled dot over -9. As r is smaller than or equal to -9, you attach an arrow to the dot above the -9, pointing towards the -10 side (more negative side).

Answer 2

Draw a number line.

Place a closed filled in circle at -9. Then shade to the left.

This visually indicates r = -9 or r < -9
