Answer:
D) 2/5 miles/minute
Explanation:
In order to find the slope of the line (m), we will use the following expression.
m = y₂ - y₁ / x₂ - x₁
where
(x₁, y₁) and (x₂, y₂) are any two points through which the line passes.
When the time is 0 minutes (x₁ = 0 min), the miles traveled are 0 miles (y₁ = 0 miles).
When the time is 15 minutes (x₂ = 15 min), the miles traveled are 6 miles (y₂ = 6 miles).
The slope of the line is:
m = 6 mi - 0 mi / 15 min - 0 min = 2/5 mi/min
