Key Concepts

Linear Functions

A linear function represents a relationship between two variables where the rate of change is constant. This type of function is characterized by a straight line when graphed and models scenarios involving constant rates, making them fundamental in algebra and real-world applications.

Slope-Intercept Form

The slope-intercept form of a linear equation, given as y = mx + b, expresses the relationship between variables in terms of the slope (m) and the y-intercept (b). This form is useful for quickly identifying how the dependent variable changes with respect to the independent variable and for graphing the equation.

Substitution

Substitution is a method used to evaluate expressions or functions by replacing variables with specific numerical values. In the context of a linear function, substitution involves plugging in a particular value for the independent variable (x) to compute the corresponding dependent variable (y).

Table of Values

A table of values systematically lists pairs of input values and their corresponding output values for a function. It is an effective tool for understanding the behavior of a function, checking consistency of the linear relationship, and preparing for graphing the function.
