## Summary: Algebra

When faced with an algebraic expression or equation, there are only two types of things you can do to it without changing the quantitative relationship that it describes. Re-write one or more terms in an equivalent form This can be done to any expression (no equal sign) or equation (with an equal sign) at any …

## Keep Your Eye On The Variable

The following equations all have a similarity: \$latex y = |x - 8| + 5\\*~\\*y  = 4(x - 6) - 7\\*~\\*(x - 3)(13x + 11) = 0\\*~\\*y = (x + 1)^2 - 9&s=2&bg=ffffff&fg=000000\$ The similarity is that they all have expressions like (x- 6) or (13x + 11), which are often either translations or factors. …

## Analyzing Linear Equations: a summary

Explanation of key linear equation concepts: slope, intercepts, and equation forms. Discussion of how slope-intercept form, point-slope form, and standard form are related to one another. Includes general descriptions of the various starting points a student is likely to encounter in problems, and how to proceed from there.
