The Introduction to Linear Functions lesson by Media4Math is designed for high school students to grasp the fundamentals of linear functions, their properties, and real-world applications. Aligned with Common Core Standards F.IF.4 and F.LE.1, this lesson emphasizes understanding linear functions through equations and graphical representations.

This lesson focuses on the application of linear functions in real-world contexts, helping students develop mathematical models to analyze and interpret relationships between variables. Students will explore various linear models, including business growth, water levels, budgeting, and physical laws such as Hooke’s Law and Boyle’s Law.

Key components of this lesson include:

In this lesson, students will explore direct variation, a special type of proportional relationship where one variable is a constant multiple of another. They will learn how to identify direct variation in tables, graphs, and equations, determine the constant of variation ($k$), and understand how direct variation relates to linear functions.

Key concepts covered in this lesson include:

In this lesson, students explore the properties of parallel and perpendicular lines in coordinate geometry. They will learn how to identify these lines based on their slopes, determine equations for parallel and perpendicular lines, and apply these concepts to solve real-world and mathematical problems.

Key concepts covered in this lesson include:

This lesson is the third installment in Media4Math's comprehensive six-part series on understanding slope in mathematics. It focuses on helping students visualize and comprehend slope by engaging in hands-on activities that involve plotting points on a coordinate plane and analyzing the resulting lines.

This lesson is the sixth and final installment in Media4Math's comprehensive six-part series on understanding slope in mathematics. It focuses on interpreting slope as a rate of change between two quantities, enabling students to apply this concept to real-world scenarios and mathematical problems.
