Answer:

Step-by-step explanation:

First you would plot the points- (0,2), (1,4), (2,6), (3,8)

Then if the points make a straight line when you connect them then it makes it a linear equation

To know if it is proportional or not you take the y points and put them over their x points, and if all of them end up with the same number than it is proportional

2/0=0, 4/1=4, 6/2=3, 8/3=8/3, therefore it is not proportional

A marathon takes place each year.In 2020 there were 6500 runners.Does this predict that in 2023 there will be more than 7500 run

777dan777 [17]

Answer:

yes

there would be 7525 runners

Step-by-step explanation:

The formula for calculating future value:

FV = P (1 + r) n

FV = Future value

P = Present value

R = interest rate

N = number of years

6500 x (1.05)^3 = 7525 runners
