Understanding Rates and Equations

The video tutorial explains the concept of rate in equations, using a sample problem where a tutor charges $90 for six hours of work. It demonstrates how to identify independent and dependent variables, solve for the rate, and create a table to match the story problem. A new problem involving red and blue pieces is introduced, highlighting an additive relationship. The tutorial emphasizes understanding constants and applying them to different scenarios.

• a^2 + b^2 = c^2

In the equation y = KX, what does 'K' represent?

• The dependent variable

• The independent variable

• The constant rate

• The total cost

What is the independent variable in the equation y = KX?

• None of the above

• Y
