You can put this solution on YOUR website! slope = m
m = dy/dx
m = (120000-0)/(7000-15000)
m = -15
---
y - 120000 = -15(x - 7000)
y = -15(x - 7000) + 120000
where:
x = distance traveled (must be between 7000 and 15000 miles)
y = maximum payload (pounds)
---
example 1:
x = 7000 miles
y = -15*(7000 - 7000) + 120000
y = 120000 pounds
---
example 2:
x = 11000 miles
y = -15*(11000 - 7000) + 120000
y = 60000 pounds
