Chapter 2: Section 4 Notes
By the end of the section, you should be able to:
- Write and graph a linear equation in Point-Slope Form given two points, or a point and the slope.
- Write and graph a linear equation in Standard Form Students will be able to convert between all three forms of a linear equation (Standard, Slope-Intercept, and Point-Slope).
- Graph a parallel line or perpendicular line to a given line.
Definitions:
- Point-Slope Form: [y - y1 = m ( x - x1)] where a point is the ordered pair (x1, y1) and m is the slope.
- Standard Form (of a linear equation): Ax = By = C where A and B are integers and both A and B do not =0
- Parallel Lines: two lines that have the same slope.
- Perpendicular Lines: two lines that have opposite/negative reciprocal slopes (cross at a 90° angle)
