Linear Functions

Description

This example showcases the transformation of the linear equation 28x - 21y = 0 from standard form to slope-intercept form. The process involves isolating y and dividing by its coefficient, resulting in y = 4/3 x. This step-by-step solution clearly reveals the slope and y-intercept of the line.

Linear functions are fundamental mathematical concepts that describe straight-line relationships between variables. The examples in this collection, showing step-by-step transformations from standard form to slope-intercept form, help students understand how each part of the equation affects the graph and the underlying relationship.

Exposure to multiple worked-out examples enables students to identify patterns across various representations of linear functions. This reinforces their algebraic skills and enhances their conceptual understanding of linear relationships.

Teacher Script: "As we transform this equation, pay attention to how the coefficients change. What does this tell us about the line's slope and y-intercept? How might this line compare to those we've seen in previous examples? Can you think of a real-world situation where a line with a positive slope passing through the origin might be applicable?"
