Solve the system of equations by graphing. Then classify the system.
y=-x-13
4x-3y=-17
----------------
Substitute for "y" and solve for "x":
4x - 3(-x-13) = -17
---
4x + 3x + 39 = -17
7x = -56
x = -8
------------------
Since y = -x-13, y = 8-13 = -5
---
Solution: (-8,-5)
----
Since there is one point of intersection the system
is independent or consistent (whichever term you
wish to use).
