    X = 2
    Y = -2.5
    Slope = 1.250

    Eq1: 5x - 4y = 10.
    Eq2: 2x + 8y = 4.
    Multiply Eq1 by 2 and add the Eqs:

    10x - 8y = 20.
    +2x + 8y = 4.
    Sum: 12x = 24,m X = 2.

    In Eq2, replace x with 2:
    2*2 + 8y = 4. Y = 0.

    M1 = -A/B = -5/-4 = 1.25.
    M2 = -2/8 = -0.25.
