Question

If a graph is plotted by taking the temperature in Fahrenheit along the Y-axis, and the corresponding temperature in Celsius along the X-axis, then the graph will be a straight line,

• A. having a positive intercept on the Y-axis
• B. having a positive intercerpt on the X-axis
• C. passing through the origin
• D. having negative intercepts on the X and Y axes.

Answer 1

The correct option is A having a positive intercept on the Y-axis

We know, relation between Celsius-Temperature Scale and Fahrenheit-Temperature scale as $T°C=(T+32)°F$

So, if we plot graph by taking temperature in $°F$ along $Y-$ axis and using $\left(1\right)$ we have

$\Rightarrow 0°C=32°F$

So, it will intercept $Y-$ axis. $(+ve)$

Hence, the answer is having a positive intercept on the $Y-$ axis.
