Direct Variation and Earnings Calculation

The video tutorial explains direct variation through a word problem involving earnings based on hours worked. It identifies the dependent and independent variables, calculates the constant of variation, and applies the direct variation equation to solve a new problem. The tutorial concludes by summarizing the direct variation concept.

What is the main concept introduced in the video?

• Direct variation

• Indirect variation

• Inverse proportion

• Linear regression

In the context of the problem, what does the variable 'Y' represent?

• Number of hours worked

• Constant of variation

• Amount of money earned

• Rate of pay

What is the formula for direct variation?

• y = k / x

• y = m * x + b

• y = k * x

• y = x / k
