Today we learned the Pythagorean Theorem. We can use this formula to find the missing side lengths of right triangles. Refer to your notes and examples if you need help when working on your homework.
HW~#1-26 p. 595

Monday, March 28

Today we started Chapter 11 which focus is right triangles. Before we start with right triangles, we had to learn about irrational number and square roots. Remember irrational numbers are decimals that do not repeat and go on forever & ever.

Today we reviewed for the test on Chapter 8. This is going to be one of the most challenging tests so far but all of you have been doing a great job in class. I know that you are going to do GREAT!! Remember to study tonight by doing problems and also make your notecard cheat sheet.
HW~STUDY FOR QUIZ!!!
Extra Credit - #9-39 p. 453-455

Tuesday, March 22

Today we corrected homework from last night, went over the quiz we took last week Friday, and started to review for the test. If you finished your Practice Test in class, you should start studying tonight. You can fill out a notecard to use on the test. Here are somethings I recommend that you have on your notecard:

• How to tell if a relation(set) is a function
• Formula for slope and an example
• y = mx + b where m = slope, b = y-intercept, and (x,y) is a point on a line
• steps for graphing a linear equation
• steps for graphing a linear system
• steps for graphing a linear inequality
• how do you know if it is a dashed or solid line
• where do you shade
• graphing linear inequality systems
• scatter plots & trend lines

This is going to be one of the hardest tests you have taken so far so be sure to study!!

Monday, March 21

Today we learned how to graph linear inequalities and linear inequality systems. Everyone caught on very quickly because it it very similar to graphing linear equations. The only difference is the line that is drawn, it is either dashed or solid, and the graph is shaded.

Remember, Friday is the last day of the marking period, so the last day you can turn in missing work or make up quizzes is Wednesday.

HW ~ 8-8 Worksheet

Thursday, March 17

Today we spent the day review systems of equations and how to solve them by graphing. It seems that all of you have a much better understanding after working in groups. I think that you will be better prepared for the quiz which was postponed to tomorrow, Friday.
HW~finish last 3 problems on worksheet & study for quiz

Wednesday, March 16

Today we learned how to solve systems of equations. This means that we found the solution that 2 equations have in common or where the 2 line intersect. Remember when graphing lines, first graph the y-intercept, then use slope to find 2 or 3 more points on the line. Finally, connect those points together with a line.
HW~#2-16 (evens) & #20-24 (evens) p. 442
QUIZ TOMORROW on 8-5 to 8-7!!!!

Tuesday, March 15

Today we learned two new things. First, we learned how to write an equation or rule for a line given 2 points. The steps for doing this are the following.
1. Find the slope.
2. Using the slope and a point find the y-intercept.
3. Rewrite the equation in slope-intercept form, replacing m and b.

The second thing we learned was how to draw a trend line and write and equation for that trend line. We can use the trend line to estimate information on the graph.

HW ~ WORKSHEET - QUIZ ON THURSDAY!!!

Monday, March 14

Today we went over the quiz. I am so proud of all of you. You did a great job!! Today's lesson covered scatter plots. We did an activity where we compared height and hand span. We talked about how scatter plots have positive correlation, negative correlation, or no correlation.
HW~#1-3, 7-15 p. 430

Monday, March 7

Today we continued the lesson from last week Thursday on Slope & Y-Intercept. Thursday we learned how to calculate slope. Today we learned what the y-intercept is and how to use slope and y-intercept to graph lines.
HW~ ALL PROBLEMS MUST BE GRAPHED - 10 Graphs!!!
#11-19 (odds) & 31-39(odds) p. 418-419

Friday, March 4

Because over half the class was gone today at Band Festival, we just reviewed slope some more. There is no homework this weekend. Remember to be studying the notes that we take in class because this is all new and it can be challenging!!

Thursday, March 3

Today we learned about slope, and that it is the slant of a line. We learned to calculate slope by using points on a graph and calculating the rise over run. We also learned how to calculate the slope when given 2 points, we used the formula for slope.
Homework is modified tonight because I ran out of class time to explain everything, so tonight's homework is listed below. We will finish the lesson Monday because most of the class will be gone to band festival. For those of you left behind, we will do some more practice with slope.
HW~#1-10 p. 418

Wednesday, March 2

Today we continued Chapter 8 as we graphed equations. When we graphed today, we used a t-chart to record all our x & y values and then we graphed the points and connected them with a straight line.
