Answer:
Part A and Part C : Let x represents the number of hours and y represents the earning after x hours,
As per statement,
The earning is $5 for an hour,
Thus, the earning for x hour = 5x
⇒ y = 5x -----(1)
Which is the equation that shows the relationship between the two variables ( x and y ),
Since, earning is dependent on the time,
⇒ y is dependent variable and x is independent variable,
Part B :
From equation (1),
For x = 1, y = 5,
For x = 2, y = 10,
For x = 3, y = 15,
Hence, the possible order pairs that shows the value of the values of the two variables are (1,5), (2, 10) and (3, 15).
