Question

Below are given functions for number of apples bought by 2 customer in some days.


For the function representing customer , slope is more.

• A. A
• B. B
• C. None

Answer 1

The correct option is B B


Let us consider two points on the graph, say (2,20) and (4,40)

$\text{We know, slope (m)}=\frac{\text{Change in y}}{\text{Change in x}}$

$=\frac{40-20}{4-2}$

$=10$

Therefore, the slope of function representing customer A is 10

For customer B:


The given two points are (7,84)
and (9,108)

$\text{We know slope (m)}=\frac{\text{Change in y}}{\text{Change in x}}$

$=\frac{108-84}{9-7}$

$=12$

Therefore, the slope of function representing customer B is 12.

Hence, function representing Customer B has more slope compared to Customer A.
