please help.

Answer 1

linear function means that the equation of the line will have the form

y=mx+b
where y is the weight of the plane and x is the number of gallons

Answer 2

you know that 10 gallons is related to 1958 pounds, so we can denote this as the ordered pair
(10,1958)

you know that 45 gallosn is related to 2161 pounds, so we can denote this as the ordered pair
(45,2161)

we have 2 ordered pairs, so we can determine the slope (weight per gallon) of the linear function

Answer 3

would you do 1958 / 10 and then 2161 / 45?
