Question 613723: Solve the system of equations by graphing. Then classfy the system.
x+y=15
X-y=3

Graph the two equations to get




Note: the first equation x+y=15 is in green and the second equation x-y=3 is in blue

We see that the two lines intersect at the point (9,6). So the solutions are x = 9 and y = 6

So the system is consistent and independent.
