Question

Find the slope of the line $y=0.$

• A. $0$
• B. $1$
• C. Not defined
• D. $2$

Answer 1

The correct option is A $0$

Equation of the line: $y=0$
$\begin{array}{cc}x& y\\ 0& 0\\ 2& 0\end{array}$
Let the slope of the line be $m$.
$m=\frac{\text{change in y}}{\text{change in x}}=\frac{0-0}{2-0}=\frac{0}{2}=0$
Since the slope is $0$ and the point $(2,0)$ lies on the why axis, the required line lies on the x-axis.
