Essential Questions
Patterns and relationships
can be represented
graphically, numerically,
symbolically, and verbally.
What makes a relationship linear?
Glencoe Resource
Why are linear functions useful?
Why are patterns and relationships represented in multiple ways?
Linear relationships are
characterized by a constant
rate of change.
Indicators
1.8.1.1 use written, oral, and symbolic language to identify and describe patterns, sequences, and
functions.
1.8.1.2 determine whether functions are discrete or continuous.
1.8.3.2 solve problems involving direct and inverse variation.
1.8.3.3 determine the rate of change (slope) of a linear function when represented graphically.
1.8.4.1 represent quantitative relationships graphically and interpret the meaning of a specific part of
a graph in the situation represented by the graph.
1.8.5.1 verify that points lie on a line, given an equation of the line.
1.8.5.2 graph linear equations on a coordinate plane.
4.8.3.2 make predictions about a set of data given the line of best fit.
4.8.3.3 fit a line to a set of data and make a prediction about the data.
