I think you are missing part of the problem. If you had another equation or a value for x you could solve it.
The graph would intercept at (0,-4) on the y-axis & at (5.3,0) on the x-axis. And the shaded region would be on the right side of the line on the graph.
Answer: I think its 81 but i'm not that sure.
Step-by-step explanation:
1 2/5 + 3 1/2

= ((7x2)+(7x5))/(5x2)
=(14+35)/10
=49/10
=4 9/10
