Question

Suppose that the weight (in pounds) of an airplane is a linear function of the total amount of fuel (in gallons) in its tank. When graphed, the function gives a line with a slope of
6.1
. See the figure below.
With
50
gallons of fuel in its tank, the airplane has a weight of
2205
pounds. What is the weight of the plane with
19
gallons of fuel in its tank?

Answer 1

I have to find the angle of the graph?

Answer 2

linear relationship between weight & amount of fuel

(y-2205)=m(x-250)
according to question
m=6.1

therefore linear relationship (y-2205)=6.1(x-250)

Answer 3

u r asked to find weight when amount of fuel is 19 gallons

put x=19 gallons in the linear relationship & find y.

the value of y will be the answer

Answer 4

gt it ?

Answer 5

Thank you so much!
