Question 435120
solve the system of equations by graphing then to classify the system?
x + y =9
x - y = -5
----
Solve each equation for "y":
y = 9-x
y = x+5
----
Note: the slopes are different so the system is consistent;
the equations are independent.
-----
Graph each line on the same axis and find the point of intersection.
(2,7)

{{{graph(400,300,-10,10,-10,10,9-x,x+5)}}}
