WELCOME TO CAHSEE

Week Three

NOTES- any slide with a green title should be written down in your notebook.

Lesson #5- Algebra 4.0

Simplifying Expressions (7 mins)

•Distributive Property- distribute the number and variable to the numbers and variables inside of the parentheses.

• Combine Like Terms- adding or subtracting terms with the same variables or terms.

Distributive Property

Distribute the 5 to everything inside of the parentheses

5(10x -6) =4 50x – 30=

4

Distributive Property/ Combining Like Terms

Distribute the x and then the 9

x(9-6) + 9(x-2) > 80

9x-6x + 9x-18 > 80

12x -18 > 80

Combine like terms, remember to combine the – or + sign

Bootcamp Practice (15 mins)

Pages 115- 116- you may not write on. Copy the questions into your composition notebook and solve.

Lesson #6- Algebra 6.0

Graph Linear Equations- 7 mins

Slope intercept form (y= mx +b)

Y-intercept- where the line crosses the y-axis.

X- Intercept- where the line crosses the x- axis.

Find the x and y intercepts- 10 mins(plug in (0) to solve for each.

y= -3x- 2 y= - 3 (0) -2y= -2

y= -3x- 2 (0)= - 3x -2 +2 +2

2= -3x -3 -3-2/3= x

Find the x- and y- intercepts (plug in known info below) Y= x+3

X 0 1 2 -1Y 3 1 0

Example: Y= (1) +34= 4

Put equation in slope intercept formy= mx +b

4x +2y= 6- 4x -4x2y= -4x +6 2 2 2Y= -2x +3

4x +2y= 6

To find the slope of a lineUse the formula (- (- (4, 5) (9, 7)

Solve (7-5) = 2 (9- 4) 5

Slope = (positive slope)

Graph the equationY= -2x +3

Rise= -2 Run 1
