Answer 1

Answer:

y = 10.50x + 7.50

Step-by-step explanation:

First find the slope

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

   Add the two y values  to get the total y for the slope

y2 = 5.50+4 = 9.50  when x=2

y1 = 3.50+ 2.50 = 6  when x =1

m = ( 9.50-6/(2-1)

    3.50/1

  = 3.50

The slope intercept form is

y = mx+b  where m is the slope and b is the y intercept

y = 3.50x +b

Using the point ( 1,6)

6 = 3.50(1) + b

6 - 3.50 = 3.50+b-3.50

2.50 =b

y = 3.50x+2.50

We want 3 shipments

Multiply by 3

y = 10.50x + 7.50
