If a data line on a graph slopes down as it goes to the right, it is depicting that
1. as the value of one variable falls, the value of the other also falls (all else constant).
2. the relationship between the variables on the axes is direct.
3. the relationship between the variables on the axes is inverse.

Solution:

If a data line on a graph slopes down as it goes to the right, it depicts that the relationship between the variables on the axes is inverse. {option (c)}

Let the values by graph be; when x = 10, y = 100; x = 20, y = 90; x = 30, y = 80, and so on.

We observe that as the value of ‘x’ increases, the value of ‘y’ decreases hence, x and y have an inverse relation.

If a data line on a graph slopes down as it goes to the right, it is depicting that
1. as the value of one variable falls, the value of the other also falls (all else constant).
2. the relationship between the variables on the axes is direct.
3. the relationship between the variables on the axes is inverse.

Summary:

If a data line on a graph slopes down as it goes to the right, it depicts that the relationship between the variables on the axes is inverse.
