Key Concepts

Slope Calculation

The slope of a line measures its steepness or rate of change and is calculated as the ratio of the difference in the y-values to the difference in the x-values between two distinct points on the line. This concept is central to linear functions, as it quantifies the relationship between the variables and is used in the slope-intercept form.

Linear Function

A linear function is a function whose graph is a straight line. It is typically expressed in the slope-intercept form (y = mx + b), where m represents the slope and b represents the y-intercept. Understanding linear functions involves comprehending how changes in the independent variable result in consistent changes in the dependent variable.

Function Evaluation

Function evaluation involves computing the output of a function for a given input by substituting the input value into the function's equation. This process is key in verifying the behavior of a function at specific points and is fundamental in understanding how a function maps inputs to outputs.

Horizontal Line

A horizontal line is characterized by a constant y-value for every point along the line. In other words, regardless of the x-coordinate, the y-coordinate of any point on a horizontal line remains the same. This concept is fundamental in coordinate geometry and is used to represent situations with no vertical change.

Vertical Line

A vertical line is defined by a constant x-value for all its points; the x-coordinate remains unchanged while the y-coordinate can vary. Vertical lines have a special property in that they do not represent functions of x, as they fail the vertical line test (i.e., for a given x-value, there are infinitely many y-values). This distinction is important when defining or analyzing functions.
