Wednesday: Review how to write equations of lines given various information. If time...start Thursday's work.
In-class work: http://images.pcmac.org/SiSFiles/Schools/AL/AlbertvilleCity/AlbertvilleHigh/Uploads/DocumentsCategories/Documents/Writing_the_Eqns_of_lines.pdf

Thursday:
Our learning target is to understand how to set up an equation in slope intercept form from real world information and utilize the equation and graph to make predictions and determine answers.
Watch the following three story problem videos and complete the guided practice sheet : Unit 3 Slope Intercept Story Problem Guided Practice.docx
VIDEO 1.
VIDEO 2.
Additional video: https://braingenie.ck12.org/skills/105429 (CHOOSE WATCH VIDEO)
Practice identifying independent and dependent varialbes:
Friday:
ENTRANCE QUESTION: Convert this equation into slope intercept form: -3x + 4y = 16
We will review the Video Guided Practice sheets from Wednesday and then investigate what the slope in real world problems really means and how to recognize it from a graph.
Can you identify independent and dependent variables correctly? Let's look at this activity sheet and practice with your partners: it_all_depends_on....._classifying_dependent_versus_independent_variables_.pdf
We will then use the following resource to help us understand slope in the context of a story problem. Partners will each be assigned one problem to "master", then they will share out with the entire class: Meaning of Slope Rate of Change in Graphs.pdf to help us understand slope in the context of a real world problem and how to begin setting up equations in slope intercept form from a story problem.

Complete this homework for tomorrow, including your graphs.
Monday-Tuesday
Here are a few hints for your homework due tomorrow:
HOMEWORK_SlopeInterceptform.docx
1. The slope intercept form of the equation that represents the situation in the first rental car example is:
y = .25x + 32 or y = 1/4x + 32
2. The slope intercept form of the equation that represents the second rental car question on the back is:
y = -1/25x + 15
3. What makes a good graph? Click here!
4. You might want to make a table of values to graph these equations. (choose some values for x and solve for y to get ordered pairs to graph).
Wednesday:
Our learning target for today is: Students will understand how to create a line of best fit from a set of data.
Go over the Avis car rental.
We will use the following notes: Line of best fit and correlations.notebook
