Notes:
Expression: A collection of numbers, variables, and signs, such as 3,3x+4,5x2+2,x−3, 3, 3x+4, 5 x^2 + 2, \sqrt{x-3}, etc

Equations: A mathematical statement with an equal sign, such as y=2,y=3x−2,y=x,x=3, y = 2, y = 3x-2, y = x, x = 3, etc

Linear
Equation: Ax + By = C (A, B & C are constants; x & y are variables)
All linear equations are functions except a vertical line such as x = 3.
