    Solve for Y.

    3Y + 8X + 3 = 19 + 8X

    Subtract 3

    3Y + 8X + 3 - 3 = 19 - 3 + 8X

    3Y + 8X + 0 = 6 + 8X

    3Y + 8X = 6 + 8X

    Subtract 8X

    3Y + 8X - 8X = 6 + 8X - 8X

    3Y + 0X = 6 + 0X

    3Y = 6

    Divide by 3

    3Y/3 = 6/3

    Y(3/3) = 6/3

    Y(1) = 2

    Y = 2

    Done.

    Y-intercept is the constant term, 2
    Slope is the coefficient on X, 0
