Answer:

Step-by-step explanation:
step 1
Find the equation of the solid line
Find the slope
we have
(0,0.2) and (3,2.2)

The y intercept b is equal to

so
the equation of the solid line in slope intercept form is equal to

step 2
Find the equation of the inequality
we know that
The solution of the inequality is the shaded area below the solid line
therefore

Answer:
(x + 2)/x
Step-by-step explanation:
(x + 2) × 1/x
= (x + 2)/x
