September 22nd (A) and 23rd (B)

7.1 and 7.2 SOLVING INEQUALITIES

I can...
~solve an inequality using +, -, x, /
~graph solutions on a number line
~give solutions using Set-Builder Notation

Properties of Inequalities
1. You can add or subtract the same number from both sides.
2. You can multiply or divide by the same POSITIVE number on both sides.
3. You can multiply or divide by the same NEGATIVE number on both sides AND change the direction of the symbol.

Assignment:
p. 388 (#17-32) work the first half using a graph/work the second half using Set-Builder Notation
p. 396 (#20-31)

September 10th (A) and 13th (B)

Review #8 - Slope-Intercept Form

Slope-Intercept Form: given the slope m and y-intercept (b) of a line, the slope-intercept form of an equation is: y = mx + b

m = slope
b - y-intercept
