Corey walked three blocks east and then six blocks north. All the blocks were the same length. What is the value of the slope of the line from where Corey began walking to where he finished?

Slope is the change in the north-south direction divided by the change in the east-west direction. Corey went 6 blocks north and 3 blocks east, so the slope is 6 ÷ 3 = 2; the correct choice is 2.
