    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 y=-2.5x+1.5, so the system is consistent and dependent with infinitely many solutions.
