Answer:
They distort differences between values.
Step-by-step explanation:
Non-zero axes distort differences between values, but they are not always misleading.
It depends on who is looking at them.
Consider the bar graphs below, showing the change in interest rates over time.
A naïve reader might conclude that interest rates had risen sharply (the zero-axis shows that they have remained steady).
However, a professional who specializes in interest rates might find the information in the left-hand graph quite useful.
Remember, the sides are labelled with lower case letters, and angles are labelled with CAPITAL letters. The angles are labelled with the CAPITAL letter that is opposite from the side with that letter.
so:
Angle A is opposite side a
Angle B is opposite side b
Angle C is opposite side c
The two variables present here would be the value of the car, and the time is depreciates for. Time is the independent variable, because it is not affected by the value of car. Since the value of the car is a function of the time, therefore, it is the dependent variable.
