! The regression equation y = 3.648 • 1.182^x approximates the cost to go on a safari, y, given the number of years since it opened in 2005, x. Which is the best estimate for the cost of a vehicle to drive through the safari in 2011?
If you look at both of the slopes, you can tell that 6/10 is actually equivalent to 3/5. 3/5 is the simplified version of 6/10. So realistically, they'd line up perfectly and not be parallel!
