Algebra 23 - Two-Point Form
The two-point form of the equation for a line can describe any non-vertical line in the Cartesian plane, given the coordinates of two points which lie on the line.

Algebra 24 - Standard Form
The standard form of the equation for a line Ax + By = C can describe any line in the Cartesian plane, including vertical lines. The constants A, B and C have no special meaning, but in combination they tell us many things about the...

Algebra 21 - Slope
"Slope" is a fundamental concept in mathematics. Slope is often defined as "the rise over the run" ... but why?

Algebra 22 - Point-Slope Form
The point-slope form of the equation for a line can describe any non-vertical line in the Cartesian plane, given the slope and the coordinates of a single point which lies on the line.
