Learning Outcomes
By the end of this lesson, you will be able to:
- Graph linear functions by plotting points, using the slope and y-intercept, and using transformations.
- Write the equation of a linear function given its graph.
- Match linear functions with their graphs.
- Find the x-intercept of a function given its equation.
- Find the equations of vertical and horizontal lines.
- Determine whether lines are parallel or perpendicular given their equations.
- Find equations of lines that are parallel or perpendicular to a given line.
- Graph an absolute value function.
- Find the intercepts of an absolute value function.
We can now describe a variety of characteristics that explain the behavior of linear functions. We will use this information to analyze a graphed line and write an equation based on its observable properties. From evaluating the graph, what can you determine about this linear function?
