Standard Form of a Line

"We will commonly see lines expressed standard form, especially when we look at and write systems of linear equations. The standard form of a line puts the x and y terms on the left hand side of the e ...

Slope-Intercept Form of a Line

"Slope-intercept form of a line is a general formula for the equation of a line. Using the slope-intercept form of a line helps in finding the slope of a line from an equation and the intercept direc ...

Slope

"One of the most important things to understand about lines is the slope. Slope is the 'steepness' of the line, also commonly known as rise over run. We can calculate slope by dividing the change in t ...

Rectangular Coordinate System

"In Algebra, we often use the rectangular coordinate system to graph lines, parabolas and other formulas. Important terms to be familiar with include the y-axis, the x-axis, y-coordinates, x-coordinat ...

Point-Slope Form of a Line

"Point-slope form of a line is one method to write the equation of a line. Start with the slope equation, which is basically the difference between two points, and then rearrange the terms to obtain ...

Midpoint Formula

"A midpoint is the halfway point between two points on a coordinate axis. To calculate the midpoint, we use the midpoint formula which is the average of the x-values and the average of the y-values. T ...
