Linear Functions
Build confidence with slope, equations, graphs, and real-world linear models.
Why it matters
Linear functions show up across Math 1: tables, graphs, word problems, scatter plot models, and comparison questions. A steady slope strategy makes the rest of the course feel more connected.
Key Vocabulary
Words and forms to know
These terms support equation writing, graph interpretation, and EOC-style modeling questions.
Slope
The steepness of a line, found by comparing vertical change to horizontal change.
Rate of Change
How much the output changes for each 1-unit change in the input.
Y-Intercept
The output value when the input is 0; where a graph crosses the y-axis.
X-Intercept
The input value when the output is 0; where a graph crosses the x-axis.
Slope-Intercept Form
A line written as y = mx + b, where m is slope and b is the y-intercept.
Standard Form
A linear equation written as Ax + By = C.
Point-Slope Form
A line written using one point and the slope: y - y1 = m(x - x1).
Parallel Lines
Lines in the same plane that never intersect and have the same slope.
Perpendicular Lines
Lines that meet at a right angle and have slopes that are opposite reciprocals.
Linear Model
An equation, graph, or table that represents a constant rate of change.
