Question

The vaccination report for cattles and birds are given in table and graph below.

Cattle vaccination report:

Birds vaccination report:
Find which among these two are vaccinated more often.

• A. Birds
• B. Cattles
• C. Both are equally vaccinated.
• D. Cannot be determined

Answer 1

The correct option is B Cattles

Given cattle vaccination report:

Points are (1,7), (2,14), (3,21)

Using the information given, the vaccination for both birds and cattle are plotted on the following graph:


Comparing both the slopes

Slope for cattle = $\frac{y_2-y_1}{x_2-x_1}$
= $\frac{14-7}{2-1}$
= 7

Slope for birds = $\frac{y_2-y_1}{x_2-x_1}$
= $\frac{6-4}{3-2}$
= 2

Since the slope for cattle is steeper than birds, cattle are vaccinated more often.
