T.i.P.S.

This standard requires students to look at bivariate sets of data on graphs, such as in a scatterplot, to determine if the data represents a linear relationship or a nonlinear relationship.
Example

Which of the following does not represent a linear relationship? Justify your thinking for each answer choice.
TEKS

8.5 Proportionality. The student applies mathematical process standards to use proportional and nonproportional relationships to develop foundational concepts of functions. The student is expected to:(C) contrast bivariate sets of data that suggest a linear relationship with bivariate sets of data that do not suggest a linear relationship from a graphical representation
