When a graph between two physical quantities is a straight line, the two quantities are

Question

Verified by Toppr

Answer 1

As we know the equation of a straight line is $Y = m X + C$
Let us assume $X$ and $Y$ are two different physical quantity and C is any constant. and the graph between them is straight line.
According to above equation,
$Y \propto X$
Hence, $X$ and $Y$ are Directly proportional.
Option C

Answer 2

As we know the equation of a straight line is

Y = m X + C

Let us assume

X

and

Y

are two different physical quantity and C is any constant. and the graph between them is straight line.

According to above equation,

Y \propto X

Hence,

X

and

Y

are Directly proportional.

Option C

When a graph between two physical quantities is a straight line, the two quantities are

Both constant

Independent of each other

Directly proportional

Inversely proportional

Solution

Directly proportional

As we know the equation of a straight line is $Y = m X + C$
Let us assume $X$ and $Y$ are two different physical quantity and C is any constant. and the graph between them is straight line.
According to above equation,
$Y \propto X$
Hence, $X$ and $Y$ are Directly proportional.
Option C
