(6) Linear functions. The student understands the meaning of the slope and intercepts of the graphs of linear functions and zeros of linear functions and interprets and describes the effects of changes in parameters of linear functions in real-world and mathematical situations. The student is expected to:
- (A) develop the concept of slope as rate of change and determine slopes from graphs, tables, and algebraic representations;
- (B) interpret the meaning of slope and intercepts in situations using data, symbolic representations, or graphs;
- (C) investigate, describe, and predict the effects of changes in m and b on the graph of y = mx + b;
- (D) graph and write equations of lines given characteristics such as two points, a point and a slope, or a slope and y‑intercept;
- (E) determine the intercepts of the graphs of linear functions and zeros of linear functions from graphs, tables, and algebraic representations;
- (F) interpret and predict the effects of changing slope and y-intercept in applied situations; and
- (G) relate direct variation to linear functions and solve problems involving proportional change.
