Linear Equation
An equation that can be expressed in the form:

Ax=B
Identity
an equation that is true for all values of the variables.
Linear Inequality
An inequality that can be expressed in the form

Ax≤B
Linear Equation in Two Variables
Ax+By=C
Slope of the Line
m=Y2-Y1/X2-X1 or Rise/Run
Point-Slope Equation
y - y₁ = m(x - x₁)

Can be used to find the general equation.
Slope Y-intercept Equation
y=mx+b

m is the slope and b is the y-intercept
Perpendicular "Test" Equation
m1 & m2 are perpendicular only if:

m1=1/m2

or

m1m2=-1
