If the cards contain the following equations, what is the probability that a student will graph a line whose slope is 3?

3y = 9x + 3
x(x + 3) = 0
3x + y = 0
x = 3y
x2 + 3 = 0
y - 3x = 0

  1. 3Y = 9X + 3.
    Y = 3X + 1.
    m = 3.

    y - 3x = 0,
    -3x + y = 0,
    m = -A/B = 3/1 = 3.

    Prob. = 2/6 = 1/3.
