Compare properties of two linear functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions).
Qualitatively analyze the functional relationship between two quantities. β’ Analyze a graph determining where the function is increasing or decreasing; linear or nonlinear. β’ Sketch a graph that exhibits the qualitative features of a real-world function.
Analyze functions that model linear relationships. β’ Understand that a linear relationship can be generalized by π¦ = ππ₯ + π. β’ 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 (π₯, π¦) values or a graph. β’ Construct a graph of a linear relationship given an equation in slope-intercept form. β’ 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 π¦- intercept of its graph or a table of values.
