Answer with Step-by-step explanation:

we are given system of inequalities:

3x + 5y ≤ 9 and

2x + y ≥ 5

We have to determine the graph of the above system

In Second and third graph point (0,6) lies in shaded region

Putting (0,6) in 3x + 5y ≤ 9

3×0+5×6≤9

⇒ 30≤9 which is incorrect

Hence, second and third are not its graph

In fourth graph (0,3) lies in shaded region

Putting (0,3) in 3x + 5y ≤ 9

3×0+5×3≤9

⇒ 15≤9 which is incorrect

Hence, fourth is not its graph

Hence, the only option we are left is graph first

Hence, first graph is the correct representation of 3x + 5y ≤ 9 and

2x + y ≥ 5
