The following graph shows the relationship established by a car dealership between the sale price of a particular car model and the age of the car. write the equation for the line of best fit shown on the graph. y=

y = -2444.4444x+19000

Step-by-step explanation:

Pick two points along the line to find the slope

(0, 19000) and (4.5, 8000)

slope = (y2-y1)/(x2-x1)

        = (8000-19000)/(4.5-0)

         =-11000/4.5

           = -2444.44444444

We know the y intercept (where it crosses the y axis  (x=0))  (0, 19000)

We can write an equation using y = mx+b

y = -2444.4444x+19000

Using 2 points: (0,19,000) and (3.25, 11,000)

First find the slope by putting the change in Y over the change in X:

Slope = ( 19000 - 11000) / (0 - 3.25)

Slope = -2462.54

The Y intercept is the 1st Y value = 19,000

The equation becomes: y = -2461.54x + 19000

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
