2/15 Pre Algebra - Writing Equations Of Lines

Today students will continue their work with linear equations and graphs. In this lesson, we will not be graphing, but we will use graphs to determine the equation of a line. Students will be given one of three scenarios:

1) A slope and a y-intercept
2) A graph with two points labeled
3) The equation of a parallel or perpendicular line and the y-intercept

They will use this information to write the equation of a line. To see an example of how to do the first scenario, click on the video above. To see some explanations of the second 2 scenarios, click here.

The students took notes over some example problems, then we did a worksheet together in class for practice and finally they were allowed to work on their graded assignment due for Monday.
