Problema Solution
A plane is at 10000 feet in the air. and it needs to land in 3.2 miles. if you draw the line on a graph what will be the slope of the line.
Answer provided by our tutors
1 mile = 5280 ft
3.2 miles = 3.2*5280 ft = 16896 ft
let consider the approach slope of the plane to be the straight line between (0,10000) and (16896, 0)
the slope-intersection equation of the line is given by
y = mx + b, m is the slope, b is the y-intersect
the line goes trough (0,10000) so
m*0 + b = 10000
b = 10000
the line goes trough (16896, 0) so
0 = m*16896 + 10000
m = - 10000/16896
m = - 0.591856
the slope of the line will be - 0.591856.
