We have to write an inequality for the value of r is at most 10.

By at most we mean the value of r can be maximum 10 and not more than 10

so we use the inequality sign ≤ here

r≤10

solution on number line is shown in attachment

At most 10 means 10 or less

So representation can be r≤10

Now for graph we will just mark a point at 10 on number line then shade towards left side because r is less than 10.
