Concept explainers
(a)
Interpretation:
From the graph the value of m and b in the equation y = mx + b is to be determined.
Concept introduction:
The scope of the measurement depends upon the context and event. Measurement is commonly used as an international system of unit as a comparison framework. Two variables such as mass (m) and volume (V) can be described as directly proportional one on other by the expression m α V. Besides, the term density is given by the mass of the given substance per unit volume. Moreover, slope is the ratio of the change in the value of ‘y’ with respect to change in the value of ‘x’.
(b)
Interpretation:
The proportional relationship between x and y is to be stated.
