Question

The sales rate increases from 2 to 3.5. Analyze the given graph and find the new graph.

• A.
• B.
• C.
• D. Can't be determined

Answer 1

The correct option is A

It is given that the sales rate is increased from 2 to 3.5.

To select the correct option, we have to find a graph with slope as 3.5.

So, we move the points in such a manner that the slope becomes 3.5.

From the first option:

$\text{Slope}=\frac{Changeiny}{Changeinx}$
$=\frac{7-0}{2-0}$
$=3.5$

From the second option:

$\text{Slope}=\frac{Changeiny}{Changeinx}$
$=\frac{7-0}{2.6-0}$
$=2.70$

From the third option:

$\text{Slope}=\frac{Changeiny}{Changeinx}$
$=\frac{4-0}{1.6-0}$
$=2.5$

Only first option has a slope 3.5.

$\therefore$ First option is the correct choice.
