Answer:
see below
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
