Literal Equations, Coordinate Plane and Slope Intercept Form

A function that can be written in the form y = mx + b, where x is independent variable and m and b are real numbers. Its graph is a line.

• linear function

• quadratic function

• radical function

• piece-wise function

The slope-intercept form of a linear equation is y = mx + b, where m is slope and b is the y-intercept.

• slope-intercept form

• standard form

• point-slope form

• step function

A line described by the equation y = b, where b is the y-intercept.

• vertical line

• horizontal line

• input

• output

An equation that contains two or more variables.

• literal equation

• domain

• range

• rate

A measure of the steepness of a line. If (x₁, y₁) and (x₂, y₂) are any two points on the line, the slope of the line, known as m, is represented by the equation m= (y₂-y₁)/(x₂-x₁).

• slope

• parabola

• input

• intercept

The part of the coordinate plane on one side of a line, which may include the line.

• half-plane

• three-fourths plane

• airplane

• three-tenths plane
