System of Equations
2 students codi and kent, teamed up to solve a system of linear equations, equations 1 for cody and 2 and for kent. They made a table of values, here is the results.

equation 1
X -3 -1 1 3
Y 9 4 -1 -6

equations 2
X -2 -1 0 2
Y 6.5 4 1.5 -3.5

using the students results, what is the solution to this system of equations? (i need to put this in a graph too!)

These points fall on the same line \$\displaystyle y=-2.5x+1.5\$, so the system is consistent and dependent with infinitely many solutions.
