Interactive video lesson plan for: Linear Functions, their Attributes, & Interpreting Slope and y-Intercept

Activity overview:

I start off by giving the definition of a linear function, slope and y intercept.
At 6:15 I work through two examples of finding slope from 2 points.
At 13:05 we look at a real world setting modeled by a linear regression line and interpret the meaning of the slope and the y intercept in this real life application.
At 21:16 I graph the equation from the previous word problem using the slope and y-intercept and with the x-intercept and y-intercept. We then zoom in to the area of the graph that is appropriate to the word problem.
At 29:16 I discuss the attributes of linear graphs, like how can you identify if they will be increasing or decreasing, if there are any maximum or minimums, and horizontal and vertical lines.
