Section 1
x-intercept and y-intercept of a line
Property
The -intercept is the point where the line crosses the -axis.
The -intercept is the point where the line crosses the -axis.
The -intercept occurs when is zero.
In this Grade 7 lesson from Big Ideas Math Advanced 2, students learn to identify the slope and y-intercept of a linear equation written in slope-intercept form (y = mx + b) and use those values to graph the line. The lesson covers key vocabulary including x-intercept, y-intercept, and slope-intercept form, and guides students through deriving the slope-intercept equation from the slope formula. Part of Chapter 4 on Graphing and Writing Linear Equations, this section builds the foundational skill of connecting an equation's structure to the visual behavior of its graph.

The -intercept is the point where the line crosses the -axis.
The -intercept is the point where the line crosses the -axis.
The -intercept occurs when is zero.
Section 2
Meaning of slope
The slope of a line measures the rate of change of with respect to . In different situations, this rate might be interpreted as a rate of growth or a speed.
