Answer:

see below

Step-by-step explanation:

4a)  x / 12 = 5

    multiply both sides of equality by 12

    x = 60

4b) Dan charges $12 per hour, this doesn't change so it's the constant of proportionality.

4c) S = 12h

  If you substitute the h with the number of hours worked multiply with the  constant of proportionality 12 you'll get the amount charge S.

5) Equation for a slope is (y₂ - y₁) / (x₂ - x₁):

         (2 - 0) / (6 - 1)

         = 2/5
