Question 1006945
<pre>
She found the answers exactly, but you just wanted to estimate them.

x²+y²=49 is a circle with center at the origin and radius 7
x+y=5 is a line intersecting both axes at 5.


{{{drawing(400,400,-8,8,-8,8, circle(0,0,7), line(-11,16,10,-5), grid(1)

 )}}}



From the looks of the graph, the points of intersection look
to be about {{{(matrix(1,3,-1&3/4,",",6&3/4))}}} and {{{(matrix(1,3,6&3/4,",",-1&3/4))}}}
