The option (C) x-axis, scale: 1 unit = 1 week and y-axis, scale: 1 unit = 150 minutes with origin (0 weeks, 0 minutes) is correct.
What is a scale factor?
The ratio among comparable dimensions of an object and a model with that object, known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.
As we can see in the table, data is given, we can plot it in the graph by using the scale factor.
On the x-axis, scale: 1 unit = 1 week
On the y-axis, scale: 1 unit = 150 minutes
On the y-axis, 2 units = 300 minutes
On the y-axis, 3 units = 450 minutes
Thus, the option (C) x-axis, scale: 1 unit = 1 week and y-axis, scale: 1 unit = 150 minutes with origin (0 weeks, 0 minutes) is correct.
