We have the following inequality

$6\leq(b)/(10)$

Let's change the expression in such a way the variable b appears in the left side

Unlike equations, inequalities must attend the different comparison sign

When we flip the inequality, the comparison sign must be flipped also

$(b)/(10)\ge6$

Now we multiply by 10 on both sides to isolate the variable b. We get:

$(b)/(10)\cdot10\ge6\cdot10$

Simplifying the left side, and operating the right side:

$b\ge60$

This is our solution in written math form. We must graph it too. Of course, we already know the last option is the correct one

The graph form of the solution must include all number equal or greater than 60

Since the numbers increase to the right side, we must draw a line starting in 60 and pointing to the right side.

We must include two elements in our drawing: A solid dot which means the extreme is included in the solution

And an arrow meaning the solutions are not bounded
