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

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

To find the slope of a lineUse the formula (- (- (4, 5) (9, 7)
Solve (7-5) = 2 (9- 4) 5
Slope = (positive slope)
