The boeing 747-8 intercontinental jet can carry approximately 422,000 gallons of gasoline, making it possible for the jet to travel 14,430 kilometers before needing to refuel. using the graph, approximate the jet's average gas consumption, in gallons per hour, during the sixteen hour flight from los angeles, california to melbourne, australia. in your final answer, include all of your calculations.

The complete question in the attached figurestep 1find the slope (m)  of the equation of the line  with 2 pointspoint a (0, 422000) and    b (16,0)m=(y2-y1)/(x2-x1)=(0-422000)/(16-0)=-422000/16=-26375 gallons/hourthe value is negative because  is decreasing as time goes byy=mx+bwith the point b (16,0)0=-26375*16+b--> b=422000y=-26375x+422000[gasoline in jet in gallons]=-26375*[flight time in hours]+422000the answer is  the jet's average gas consumption, in gallons per hour, during the sixteen hour is 26375 gallons/hour
