Question

A climber is on a hike. After 2 hours, he is at an altitude of 400 feet. After 6 hours, he is at an altitude of 700 feet. What is a point-slope equation for the climber?

Answer 1

75

Explanation:

Given:

x₁ = 2 hours

y₁ = 400 ft

x₂ = 6 hours

y₂ = 700 ft

`\boxed{m=(y_2-y_1)/(x_2-x_1) }`

`m=(700-400)/(6-2)`

`=(300)/(4)`

`=75`
