A drill is used to dig down into the earth. After 2 hours, the drill is 12 meters below the surface. After 5 hours, the drill is 30 meters below the surface. Which equation represents the depth of the drill in meters, y, after x hours of drilling?A line passes through the origin and (4, 5). Which point is also on the line?
Answer: 6y = x Step-by-step explanation: All that equation is saying is that for every 1 hour drilled (x), 6 meters (y) are drilled. y = distance in meters x = time 12y = 2x 12y/2 = 2x/2 6y = x 30y = 5x 30y/5 = 5x/5 6y = x
