Determining if equations are linear - Free Math Videos - Online Tutor

The video tutorial explains how to determine if an equation is linear. It covers the standard form Y=MX+B and two key rules: no variables in the denominator and no variables multiplied by each other. The tutorial provides four examples, analyzing each for linearity based on these criteria.

What is the standard form of a linear equation?

• Y = MX + B

• Y = AX^2 + BX + C

• Y = A*B + C

• Y = A/X + B

Which of the following is NOT allowed in a linear equation?

• A variable in the denominator

• A constant term

• A variable with a coefficient

• A variable added to another variable

How can the equation Y = X/5 + 12/5 be classified?

• Exponential

• Quadratic

• Linear

• Logarithmic

Why is the equation Y = 3X^2 - 4 not linear?

• It has a variable multiplied by another variable

• It has a variable in the denominator

• It has a constant term

• It is in the form Y = MX + B

Which of the following equations is linear?

• Y = -X - 21

• Y = 7/X - X/X

• Y = 3X^2 - 4

• Y = X*Y + 5
