Answer:
-1/3= slope
Step-by-step explanation:
-6+5/6-3
= -1/3
She sailed for 7 hours and she sailed 77 hours in all
The constant of proportionality is the slope, which is found with the ratio y/x.
Let's take a point (x,y) and change it to y/x to get our constant, starting with (2,48). 48/2 = 24, so the constant is 24.
We can do the same thing with (4,96): 96/4 = 24.
Answer: 24
