Unit 2: Linear Equations

Linear Relationship

A relationship that can be represented by a linear equation between two variables, x and y.

Slope-Intercept Form

The form of a linear function written as y = mx + c, where m is the slope and c is the y-intercept.

Standard Form

The form of a linear function written as Ay + Bx = C, where A, B, and C are constants.

Y-Intercept

The y value when x = 0 in the slope-intercept form of a linear function, y = mx + c.

Slope

The rate of change of the line represented by the coefficient m in the slope-intercept form.

Linear Function

Any linear equation with two variables that meets the criteria of a function.

Linear Equation

An equation that describes a straight line when graphed, often in the form ax + by = c.

Modification of the Simple Equation

Changing the basic equation y = x by multiplying by a coefficient or adding a constant to create a linear relationship.
