Question

A factory can build 20 cars every hour.what is the slope to show this?

how many minutes have passed is the factory has built 7 cars

Answer 1

A.) y = 20x

B.) 21 minutes

Explanation:

y = mx + b; y2 - y1/ x2 - x1 = m (slope)

A.) If a factory can build 20 cars per hour, the first point would be (1, 20). To find the slope (m), divide the y-axis by the x-axis: 20/1 = 20.

B.) Before we can do this problem, we must first convert the hours to minutes. 1 hour = 60 minutes. Then we divide the minutes by the number of cars. 60 ÷ 20 = 3. That means the factory builds 1 car every 3 minutes. Multiply the number of cars, 7, by the number of minutes it takes to make one car: 7 • 3 = 21.
