Question

A boat is worth $7,000 when it is 5 years old and $2,000 when it is 10 years old. What is the slope intercept equation?

Answer 1

These are your given points:

 

(5, 7000) and (10, 2000)

 

 

The equation in slope-intercept form is

 

y = mx - mx₁ + y₁

 

where:

m = slope between the two points

(x₁ , y₁) is any of the given points
