Using LinReg to Write Linear Equations from Tables & Graphs

Flashcards covering key concepts related to linear equations, slopes, graphs, and data interpretation.

Linear Equation

An equation that describes a straight line and can be written in the form y = mx + b, where m is the slope and b is the y-intercept.

Slope

The rate of change of a line in a graph, calculated as the rise over run.

Y-intercept

The value of y when x is 0 in a linear equation, indicating where the line crosses the y-axis.

Rate of Change

The ratio of the change in the output value to the change in the input value; in the context of a linear equation, it is the slope.

Table

A systematic arrangement of data, often used to display the relationship between variables.

Graph

A visual representation of data, showing relationships between variables, often using lines or bars.

Run

The horizontal change between two points on a line, typically associated with the x-coordinate.

Rise

The vertical change between two points on a line, typically associated with the y-coordinate.

Intercept

The point at which a line crosses an axis; can refer to x-intercept or y-intercept.

Data Set

A collection of data points that can be used to calculate linear equations or analyze trends.
