Which of the following situations could be represented by the equation y = 3x + 5?

A. A bricklayer lays 5 bricks in 3 minutes. What is the total number of bricks he can lay in x minutes?

B. An express package costs $5 plus $3 per pound to ship. What is the total cost for x pounds?

C. A jogger is 3 miles from home, jogging toward home at 5 miles per hour. What is the total number of minutes it will take her to get home?

D. A math teacher gave some problems worth 5 points and a bonus problem worth 3 points. What was the total value of the problems?

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
