Which letter is in the solution set for graph #3

N

Step-by-step explanation:

Since it says y is greater then 1 it would be above the red line.

Then for the next equation, it says that y is less than the equation so it is under the blue line.

The solution is (4,1)

Step-by-step explanation:

You can tell if it is a solution by looking at the point where the two lines intersect(meet). This is why the solution is (4,1).

Elimination is best to use when there is any common factors in both equations so your can cancel them out. I'm subsititytion, its best to use if it gives you a variable. Like y = or x= and so on... and substitute that value into the other equation. I really hope that makes sense...
