How do you solve the system #x + y = -1 # and #4x + 4y = -4# by graphing?
If we simply graph these two lines we will discover that they are in fact the same line and therefore there are infinite solutions: every point in one line is also in the other.
Graphing these two lines will show that they are exactly the same line. Dividing the second equation given throughout by
As such, there are infinite solutions to this system, since there is an infinite number of points in a line, and every point that is in one line is also in the other.
