- Video 5 - Proportion, Graphing Linear Equations, Exponents
- Proportions and Problem Solving.
This segment covers applications solved by setting up and solving proportions. The importance of like units in the denominators is stressed.
- Percent and Problem Solving.
This segment covers solving problems that contain percents. Included in this segment are percent increase and percent decrease problems.
- Graphing Linear Equations.
This segment covers the slope-intercept and point-slope forms for the equation of a line. The relationship of slope to steepness and methods of calculating slope via rise over run as well as rearrangement into slope-intercept form is covered. Parallel and perpendicular lines are also covered as well as graphing inequalities by graphing their boundary equations and using a test point off the boundary to determine the solution region.
- Exponents.
This segment covers the computation of numerical expressions involving whole number exponents as well as the elementary rules of exponents.
