An activity for Year 9 students to graph three line segments, which will allow to compare human age to cat’s age.
How can we calculate cat’s age knowing human’s age and vice versa? Given a worded description, find equations of straight lines on restricted domains, graph line segments on TI Nspire or graph paper and answer all questions on the handout. This allows you to compare a human’s age to the approximate equivalent cat age in human years. Keep in mind that this is a simple linear approximation and doesn’t account for all the complexities of cat aging, but it provides a rough estimate based on three linear segments.
