Answer:
y > x + 2 and x + 2y < 4
Step-by-step explanation:
The graph to y >x+2 is shown in the attached picture, as well as the graph for 2x+2y<4, which is the same inequality as 0.5x-4< y
When you merge the 2 inequalities you get the graph that you are trying to get, the interception of the 2 regions.
You get these graphs by remembering how to inequalities are drawn, you must leave one variable on one side of the inequality sign, and the rest of terms to the other side.
Then you consider what sign you have, if is a < sign, then, is the region below the terms to the other side of the inequality, and vice versa.
