Definitions:

Vertical Line

A straight line that goes from up to down (or down to up) and does not slant; in Cartesian coordinates, it is described by an equation of the form \(x = a\).

Slope-intercept Form

An equation of a straight line in the form y = mx + b, where m is the slope and b is the y-intercept.

Slope-intercept Form

A way of writing the equation of a straight line in the form y = mx + b, where m is the slope and b is the y-intercept.

Slope

A measure of the steepness or the inclination of a line, defined as the ratio of the vertical change to the horizontal change.
