Which situation is most likely to have a constant rate of change?

Step-by-step explanation:

The constant rate of change has to represent a linear function, where the constant represents the slope of the linear function.

Basically, the constant rate of change tells about the change of the dependent variable regarding the independent variable. So, there has to be a linear relation which can be proportional, that is, the increase of one variable ensure the increase of the other variable.

So, in this case, option D shows a possible proportional relationship, because more airports visited implies more distance traveled, if one increase, the other one will too.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
