9. Slope and Linear Equations
Sections

10. Slope Slope is the steepness of a line.
It is represented by rise over run.
Formula -

11. Special Slopes Horizontal lines Slope = zero Vertical lines
Slope = undefined
Parallel lines
Slopes are the same.
Intersecting lines
Slopes are different and not perpendicular.
Perpendicular lines
Slopes are the negative reciprocal of each other.

12. y = mx + b Slope-intercept Form y-intercept
Plot a point on the y-axis using the y-intercept value.
