    1. Slope = Yb – Ya / Xb – Xa
    = 7-3/2-(-2)
    = 7-3/2+2
    = 4/4
    = 1

    2. Y-intercept
    Y = mx + b
    7 = (1)(2) + b
    7 = 2 + b
    7 – 2 = 2-2 + b (two’s cancel out and we are just left with our b on the right side)
    5 = B

    Therefore, the equation is: Y = 1x + 5 which is also the same thing as: Y= X +5.
