Question 1065176
x, gallons of fuel
y, weight of airplane
Points (x,y) from the description are (18, 2117) and (50, 2325).


Find equation of the line containing the two points.
slope {{{m=((2325-2117)/(50-18))=208/32=6&1/2}}}.
If put into point slope equation form and pick point (18, 2117), then
{{{y-2117=(13/2)(x-18)}}}.
