# Mini-Quiz: Variables and Constants in Algebra

by Ron Kurtus (revised 17 August 2012)

Take this Mini-Quiz to check your understanding of the lesson material.

1. Why would x and y be variables in the equation y = 2x + 1?

They aren't, because there are no solutions to the equation

x and y are always variables

Because there are a variety of solutions or values they can take

2. Why should you make sure you let people know that a letter designates a constant in an equation?

You really should only use numbers to represent constants

To make sure there is no misunderstanding and they think it is a variable

You don't need to bother, because most people can figure it out

3. Do you have to use a constant to represent a large number in an equation?

It is convenient but not a rule

You must use a constant for any number larger that 1000

Equations do not contain constants

If you got all three correct, you are on your way to becoming a Champion in Algebra. If you had problems, you had better look over the material again.
