1. In the graph of the system y greater than 4 x plus 9 and y less than minus 6 x plus 7, would the boundary lines be solid or​ dashed? Why? Would the boundary lines be solid or​ dashed? Why?
Â
A. The boundary lines would be dashed because they are included as part of the solution of the system whenever the system of inequalities contains only less than or greater than symbols.
Â
B. The boundary lines would be solid because they are not included in the solution of the system whenever the system of inequalities contains only less than or greater than symbols.
Â
C. The boundary lines would be dashed because they are not included in the solution of the system whenever the system of inequalities contains only less than or greater than symbols.
Â
D. The boundary lines would be solid because they are included as part of the solution of the system whenever the system of inequalities contains only less than or greater than symbols.

2. Stephanie wanted to know if the point (3,-4) lies in the region that is a solution for y > than - 2x +3 and y > than 5x-3. How could she determine if this is​ true? How could Stephanie determine if the point (3,-4) lies in the region that is a solution for y<than -2x+3 and y> than 5x-3?
Â
A.
She could determine if the point lies on either the line y equals
-2x+3 or the line y equals 5x-3. If​ so, the point lies in the region that is a solution.​ Otherwise, it does not.
Â
B.
She could substitute 3 for x and -4 for y in each inequality. If the point satisfies both​ inequalities, it lies in the region that is a solution.​ Otherwise, it does not.
Â
C.
She could substitute 3 for x and-4 for y in each inequality. If the point satisfies at least one​ inequality, it lies in the region that is a solution.​ Otherwise, it does not.
Â
D.
She could determine if the lines y equals
-2x+3 and y equals 5x-3 intersect at (3,-4).
If​ so, the point lies in the region that is a solution.​ Otherwise, it does not.
