Answer:
The constant rate of proportionality is r = 0.2
Step-by-step explanation:
We have an equation in the following format:
y = rx
In which r is the constant rate of proportionality.
To find r, we find a pair of x and y and replace.
8|1.6
This means that when x = 8, y = 1.6. So
y = rx
1.6 = 8r
8r = 1.6
r = 1.6/8
r = 0.2
The constant rate of proportionality is r = 0.2
