So if the picture on the left is correct (assuming it is…anyone, anyone?), would the point (20.4, 45) fit onto the line modeling the pound-to-kilogram relationship on the right?
The left picture is one of the many free weights I use day-to-day at the gym. The picture on the right is from a leg press machine. Answers to follow…or comment!
First, I was thinking and it should be very easy to see that the point (20.4, 45) will not fit the line on the graph.
Second, I was thinking I should reverse the axes and ask about the point (45, 20) on the pounds vs. kilos graph. This way I can teach about functions? Vertical line test?
Third, here is the line… (of the leg press machine)
