A worker is building toys at a factory. The relationship between the number of hours the employee works, x, and the number of toys the employee builds, y, is represented by the equation y = 9x. What does the equation y = 9x represent?

• A linear relationship where y is the number of toys built and x is the number of hours worked, with 9 toys built per hour.

• A quadratic relationship where y is the number of toys built and x is the number of hours worked, with 9 toys built per hour.

• A linear relationship where y is the number of hours worked and x is the number of toys built, with 9 toys built per hour.
