SWBAT… Write lines in slope-intercept form Wed, 2/20/10

There are three ways in which we can solve for slope: Slope = RISE RUN 1. Use the formula and count the spaces on a graph. = 2323.

Slope (Finding it from a graph.). Key Idea : Slope of a line is a ratio of change in y (the rise) to the change in x (the run) between any two points.

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
