Exploring Direct and Indirect Variation Concepts

What is the equation used to represent direct variation?

• x = k * y

• x = k / y

• y = k * x

• y = k / x

How can you determine the constant 'k' in a direct variation equation?

• Subtract y from x

• Divide y by x

• Add x to y

• Multiply x by y

What type of relationship do x and y have in inverse variation?

• None of the above

• Constantly equal

• Inversely proportional

• Directly proportional

What is the equation for inverse variation?

• x = k * y

• x = k / y

• y = k / x

• y = k * x

Which type of graph represents direct variation?

• Curved line

• Vertical line

• Straight line through the origin

• Horizontal line
