Question

I need to find out how much money my school loans for donating 2200 pounds of clothing

Answer 1

Firs we need to find the equation of the line

x= clothing donations (pounds)

y= Amount earned (dollars)

We have the next points

(0,0)

(100,400)

We will calculate the slope

`m=(400-0)/(100-0)=4`

Therefore the equation is

y=4x

then if x=2200

y=4(2200)

y=8800
