Question 436894: How would I solve this problem?
Graph the equations of the system. Then solve the system to find the points of intersection.
x^2 + y^2 = 49
y = x^2 - 7
Do I need to find the intersections first before I can graph?
Thank you very much for your help.

Hi

Note the use of ^ (uppercase 6)

Graph the equations of the system. 

x^2 + y^2 = 49

Using Standard Form of an Equation of a Circle is %28x-h%29%5E2+%2B+%28y-k%29%5E2+=+r%5E2

where Pt(0,0) is the center and 7 is the radius

AND

y = x^2 - 7

Using the vertex form of a parabola, y=a%28x-h%29%5E2+%2Bk where(0,-7) is the vertex

Graphing. Points of Intersection..Ordered Pairs that are solutions to this System:

Pt(0,-7), (sqrt%2813%29,6), (-sqrt%2813%29,6)
