North Carolina Standard Course of Study
Use functions to model relationships between quantities.
NC.8.F.4. Analyze functions that model linear relationships.
NC.8.F.4.a. Understand that a linear relationship can be generalized by ݑ = ưݑڰݑ + Űݑ.
NC.8.F.4.b. Write an equation in slope-intercept form to model a linear relationship by determining the rate of change and the initial value, given at least two (ݑ, Űݑ) values or a graph.
NC.8.F.4.c. Construct a graph of a linear relationship given an equation in slope-intercept form.
NC.8.F.4.d. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of the slope and ݑ-intercept of its graph or a table of values.
