3-7 Equations of Lines in the Coordinate Plane
Objective
To graph and write linear equations
Lesson Vocabulary
- slope
- slope-intercept form
- point-slope form
The Solve It involves using vertical and horizontal distances to determine steepness. The steepest hill has the greatest slope. In this lesson you will explore the concept of slope and how it relates to both the graph and the equation of a line.
Essential Understanding You can graph a line and write its equation when you know certain facts about the line, such as its slope and a point on the line.
