Hey Folks - As I said, there is a lot of new vocabulary here... you might want to go to our gooru.org class website and look at the 4-6 videos... READ the textbook... it will reinforce EVERYTHING we did today in class.
hw #4-6 pg 271 #1-7 ALL, 9,11,12-15 ALL, 18-21
Don't be fooled by g(x) and h(x)... that's just another way to say "function of x"... it's just two more versions of f(x)
f(x) is read as "f of x"
g(x) is read as "g of x"
h(x) is read as "h of x"
hw #5-7C Complete the Star Wars Handout

hw #5-7B Scatter Plots and more...
Due Fri Jan 20(B); Mon Jan 23(A)
Note: for our purposes, any references to "line of best fit" and "trend line" mean the same thing
1) Complete the "IPhone Opening Weekend Sales" problem (handout) - write a linear equation for your trend line in slope-intercept form using the technique demonstrated in class
2) Complete the "Shake it Up..." problem (flip side of handout) - write a linear equation for your trend line in slope-intercept form using the technique demonstrated in class
Challenge!! Convert both equations above to Standard Form with integer coefficients
Suggestion: Visit MathChamber Academy Unit 5 and watch the 5-5 videos and the Khan video.
pg 334 #20,21,22,24
When finished with each of the above, write each equation in standard form using integer coefficients.

hw #5-7 Scatterplots and Linear Review
Due Weds Jan 18 (B); Thurs Jan 19 (A)
pg 355 #18-31 Solve algebraically and verify visually with graphs/sketches as we have demonstrated in class. Always feel free to check your work in desmos as well. You should be a point-slope guru by the end of this lesson. There is one more problem below... it will be your HAND-IN!
Read pg 336 to understand positive, negative and "no" correlation situations. See the example on pg 337 and also read about extrapolation and interpolation. We will discuss these concepts in our next class.
Watch this video and extend the problem:
Make a copy of the graph on this video and plot all of the data points, and draw a trend line. THEN (as we did in class) select two points on your trend line (remember, they do not have to be data points) and proceed to write an equation in slope-intercept form. In order to do this, you will need to find the slope of the line and then use point-slope form. This is your HAND-IN assignment.
