Answer:
y = 27 miles
Explanation:
Given the function, y = 6x
where the slope (m) = 6 miles per hour
y = distance that the lava moved
x = average time (in hours) the lava moved
Since the question asks for you to estimate the distance (in miles) that the lava moved after 4.5 hours, then you can plug 4.5 into the equation:
y = 6x
y = 6(4.5)
y = 27
Therefore, the estimate distance that the lava flow moved after 4.5 hours is 27 miles.
