You will need to decide whether to use intercepts or slope-intercept form to graph the system of equations. Use the point tool to find the solution (point of intersection).

On your worksheet, either give your intercepts’ coordinates or slope-intercept form you use to graph your lines AND your solution (x, y) for the system.

If at any time you need more instruction on Graphing to Solve Systems, got to Cool Math for more examples.

You have assignments made on 11/28/11 to complete. Look in your messages – there should be 4 listed on 11/28/11. Solving equations (1step; 2step; multistep; proportions)You may use “the box” method or traditional method to solve.

When you complete your 10 assigned problems, go to your report to view your progress. Record this score on your paper. Or go to the messages and reply back to me with your score. Your base assignment is 10 – however, you should work to correctly complete 10. If you are still have trouble with equations, visit Cool Math Solving Equations lessons for more resources. Turn in completed work to Substitute before leaving the lab.Lots of students were attending e-Conference today with DECA.

After discussing questions from practice sheets 81 & 82 – Writing equations of lines given one-point & slope / given 2-points; Specifically page 82 #8 and 11…

#8 (4, 8) (4, -2) When we graph these points – we have a vertical line; when we calculate slope, we have undefined slope – so how do we write an equation to represent this line? What do you notice about the points? The x’s are both 4. Eq: x = 4

#11 (0, 2) (-4, 2) When we graph these points – we have a horizontal line, when we calculate the slope, we have zero slope – so how do we write an equation to represent this line? y = 0x + 2…OR we could simply look at the points, notice the y’s are both 2. Eq. y = 2

During class, we looked at writing equations for parallel & perpendicular lines. See links for examples.

3 practice problems:

Also – HW! Retake your Linear Pre-Test!

Wednesday – we check Practice Work and took Target #3 Quiz using differences / looking for patterns in tables of values.

Target #12 -= Determine if a function is even or odd.

Also, Thursday class assignment will be to retake Relations Functions Pre-Test.

Assessment Friday!

How does changing the equation of a function change the shape/position of the function’s graph?

Explore with each of the resources to determine how you can make changes to the equation and predict how if affects the graph?

Linear functions

More work with LINES…

Continue to practice translating between standard form and slope-intercept form. Target/Practice Quiz today;

HW ?:

Looking ahead to Friday – writing equations of lines given slope & a point (refer back to geogebra activity).

Use problems from pages 81 & 82 for problem sets.

Go to Geogebra

Create a line by plottting information given (either point and another point using slope, or two points).

From the graph, determine the slope and y-intercept of your line and write an equation to model the line.

Wednesday, we will algebraically write the equation to verify if your equations are correct. This will hopefully help you make connections between both the visual (graph) and algebraic (equation) models.
