Question

A company pays its employees a fixed base salary and a commission based on sales. The scatter plot shows the total earning of an employee of the company (y) based on sales (x):
*see chart attached*

Which function best represents the data in the scatter plot?

A. y = 0.1x + 10

B. y = 0.1x - 10

C. y = 0.1x + 1

D. y = 0.2x - 1

Answer 1

I believe the correct answer from the choices listed above is option A. The function that would best represent the scatterplot would be that y = 0.1x + 10. We see that the y-intercept of the plot would be at point 0,10 and the slope would be:

slope = (20-10 / 100-0) = 0.1

Resulting to an equation, y = 0.1x + 10

Answer 2

Answer: A.

Step-by-step explanation: Since when the value of sales(x) is 0 the total earnings(y) equals 10.

And the only option which satisfies y=10 when x=0 is option A

So, option A is correct
