linear function would best fit the data because as x increases, the y values change by increasing. The slope of this function is approximately 4518
What is a linear equation?
What kind of function would best fit the data, linear or exponential?
At point 1:
x = 1
y = 23,002.99
At point 2:
x = 2
y = 27,520.99
Slope, m = change in y / change in x
= (27,520.99 - 23,002.99) / (2 - 1)
= 4518 / 1
m = 2519
At point 3:
x = 3
y = 32,038.99
Slope, m = change in y / change in x
= (32,038.99 - 27,520.99) / (3 - 2)
= 4518 / 1
m = 4518
Therefore, it is a linear function.
