Can anyone help me answer these two questions?
1. Find the coordinates of the point of intersection for the graphs
I am slightly confused on how I would find x and y
The second question is graph each system of linear inequalities
x^2+4y less than 16
x^2 less than y^2+4
What I do not understand in this question is how I could get it to y=mx+b
Because whenever I move it I end up getting a negative?
