In real-life straight-line graphs, what do x and y variables typically represent?
Real-life values such as weight, length, time, speed, etc.

In a conversion graph, what is the normal practice for labeling the axes?
First named variable (e.g., p) on the vertical axis
Why are the answers obtained from a conversion graph not exact?
Because readings are taken from the graph
