Answer: No
Step-by-step explanation:
Given: The San Diego Safari Park charges $18 for parking, and an admission fee of $56.
This can be represented by the equation c = 56p + 18, where c is the total cost and p is the number of people.
Equation of direct proportion: 
But here we have a y-intercept as 18.
So, we cannot say there is a proportional relation ship between c and p.
Answer:
-5/3 = m
Step-by-step explanation:
Don't you mean (4, -1) and (1, 4)? If so, if we start with (1, 4) and move to (4, -1), then x (the "run") increases by 3 and y (the "rise") decreases by 5. Then the slope is m = rise / run = -5/3 = m
Answer:
no
Step-by-step explanation:
52/48 would simplify to 13/12
and 7/6 when multiplied by 2 would equal 14/12
