Question 188872
The problem wants me to find the points of intersection, if any, of the graphs in the system:
{{{x^2-y=5}}}
{{{-3x+y=-7}}}
----------------
If you want to graph these, dl the free software at
www.padowan.dk.com/graph/
--------------------
-3x+y = -7
y = 3x-7
Sub for y into the 1st eqn
{{{x^2 - 3x + 7 = 5}}}
{{{x^2 - 3x + 2 = 0}}}
(x-2)*(x-1) = 0
x = 1
x = 2
