# Standards Addressed

- CCSS.Math.Content.HSA-CED.A.2 Create equations in two or more variables to represent
relationships between quantities; graph equations on coordinate axes with labels and scales.
- CCSS.Math.Content.HSA-REI.D.10 Understand that the graph of an equation in two variables is
the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a
line).
- CCSS.Math.Content.8.F.A.3 Interpret the equation y = mx + b as defining a linear function,
whose graph is a straight line; give examples of functions that are not linear. For example, the
function A = s
^{2}
giving the area of a square as a function of its side length is not linear because
its graph contains the points (1,1), (2,4) and (3,9), which are not on a straight line.
- CCSS.Math.Content.8.F.B.4 Construct a function to model a linear relationship between two
quantities. Determine the rate of change and initial value of the function from a description of a
relationship or from two (x, y) values, including reading these from a table or from a graph.
Interpret the rate of change and initial value of a linear function in terms of the situation it
models, and in terms of its graph or a table of values.
