Question

A line makes an angle of $\theta$ x-axis. What is the slope of the line?

• A. $tan\theta$
• B. $cot\theta$
• C. $sin\theta$
• D. $cos\theta$

Answer 1

The correct option is A $tan\theta$

$Slope=\frac{y_2-y_1}{x_2-x_1}$
Where $y_2-y_1$ is the perpendicular distance and $x_2-x_1$ is the horizonatal distance.
$\therefore$ Slope can be written as $\frac{perpendicular}{base}$
That is same as $tan\theta$
