Which equation could represent the relationship shown in the scatter plot?
a. y=3x
b. y=5/2x-1
c. y=1/2x+7
d. y= -x+8

Step-by-step explanation:

Let's analyze each case.

case A)

This equation represent a direct variation and the relationship shown in the scatter plot does not passes through the origin

therefore

The equation case A) could not represent the relationship shown in the scatter plot

case B)

The y-intercept of this equation is equal to and the relationship shown in the scatter plot does not have points with negative y-coordinates

therefore

The equation case B) could not represent the relationship shown in the scatter plot

case C)

The y-intercept of this equation is equal to and the relationship shown in the scatter plot has points with nearest coordinates

therefore  

The equation case C) could represent the relationship shown in the scatter plot

case D)

This equation has a slope negative and the relationship shown in the scatter plot has a positive slope

therefore

The equation case D) could not represent the relationship shown in the scatter plot

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)
