Lesson Summary:

This lesson provides solutions to practice test problems in elementary algebra. The problems include simplifying exponents, rational expressions, negative numbers raised to powers, graphs with negative slope, and finding slope-intercept form of an equation. The lecturer shows two ways of getting the equation for the graph - by using the slope point formula or by visualizing it.

Lesson Description:

These are solutions to a Practice Test made for my online Elementary Algebra class.
