1. Plot the points on the graph.

2, Determine whether it is one of these: — if the points do not lie on a straight line, then it is not a linear model.

~ if after drawing a straight line between two points most of the points in between lie above the line, then it isa logarithmic model.

— if after drawing a straight line between two points most of the points in between lie below the line, then it is a exponential model.
