Question

The graph below shows the relation between the number of apples brought in some particular time.


The change in y over x = 2 and x = 4 is $\text{given as}yincreasesbym.$

What is the value of m?

• A. 2

Answer 1

The correct option is A 2
From the graph:


At x = 2, y = 20

At x = 4, y = 40

∴ Value of y is increasing from 20 to 40.

$\Rightarrow \text{y}=2\times 20$

y becomes 2 times over the interval x = 2 and x = 4.

$\therefore \text{Value of}m=2$
