Ans: B
I is true. $L_1$ is a vertical straight line and its $x$ intercept is $5$. Therefore the equation of $L_1$ is $x=5$.
I is true. $L_1$ is a vertical straight line and its $x$ intercept is $5$. Therefore the equation of $L_1$ is $x=5$.
II is false. According to the figure, the slope of $L_2$ is negative.
III is true. $L_3$ is a horizontal straight line and its $y$ intercept is $3$. Then the equation of $L_3$ is $y=3$. Hence, the point $(2,3)$ lies on $L_3$.
