Question

Can anyone show me how to figure this out.

Answer 1

Answer:

Option A (5, 0)

Step-by-step explanation:

Step 1:  Determine what is a solution

To find a solution of two lines, it has to be in the area where both of the colors intersect.  As you can see the red line goes up and the blue line goes down, but there is a shaded region where there is just white, just blue, just red, and the red and blue.  The shaded region where both red and blue is, that is where the solutions are.  

(5, 0) -> This means that the x-value is 5 and the y-value is 0 meaning that it is in the area where there is both red and blue.

(1, -3) -> This means that the x-value is 1 and the y-value is -3 meaning that it is in the area where there is only red.

(3, 3) -> This means that the x-value is 3 and the y-value is 3 meaning that it is in the area where there is only blue.

(2, 1) -> This means that the x-value is 2 and the y-value is 1 meaning that it is in the area where there is only blue.
