Let's present a solution for the generic case.
The equation will be of the form y=ax+b
If (7,3) is on it, then 3=7a+b
If (14,6) is on it, then 6=14a+b
Now we have a system we can solve.
3=7a+b => b = 3-7a
6=14a + 3-7a => 3 = 7a => a=3/7
b = 3-7*3/7 = 0
So y = (3/7)x is the equation.

Answer:
The function r(x) represents a constant rate per unit change in x.
Step-by-step explanation:
This is because when you increase in 2, it goes from 37 to 25, a decrease in 12, then when the x goes from 2 to 3, then it has to drop down by 6, or else it won't be linear. It does. 25-6 is 19. Then it goes from 3 to 5, meaning it has an increase of 2 in x, meaning it has to drop down in 12 to be linear, It does. 19-12 is 7. So it is linear, meaning it has a constant rate per unit change in x.
