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

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
