Step-by-step explanation:
These inequalities are fully simplified, so all we have to do here is graph them.
To graph x > 1, first draw the line x = 1. Since the sign of the inequality is ">", the line will be dashed, and the shading will be done above it. (This is the blue area on the graph.)
Similarly, to graph y > 1, draw y = 1. Then, because the sign of the inequality is ">", make the line dashed and shade above it. (This is the red area on the graph.)
The solution set to the system of inequalities will be the region where the two shaded areas overlap, which is the purple area on the graph below. Hope this helps!
