Note-Taking: We will practice taking thorough and helpful notes, as much of your HW will be note-taking. Your notes should always say the lesson # (P.2), date, and any objectives stated at the top. Swap and Review Notes: One a post it, answer the following questions to provide feedback on your classmates notes.

● What did these notes elaborate on and make clear? ● How could these notes be improved upon? ● What could be added to these notes to make them more thorough?

Check in: Answer the following question independently.

After watching the”Think Aloud”, I am still unsure about…

Group Work-GNAW Activity

Graphical Determine the rate of change for each section of the graph below.

Numeric Determine the slope for a line that passes through the points and . State what the slopes25,− 0)( 4 − 0, 57)( 3 are for a line parallel and a line perpendicular.

Algebraic Write the equation of a line that passes through the points

and .− , 3)( 2 9,− )( 4

Written Explain how the equation in the Algebraic section would be different if you were to write the equation for a perpendicular line. Explain how/what would be the same.

Summary ✅ EX1: A) Write the equation of a line that passes through the points (2, -4) and (0, 3). B) Write the equation of a line perpendicular to the one above.
