Embibe Experts Solutions for Chapter: Straight Line, Exercise 1: AMU-AT (B.Tech.) 2017

If the point $\left(a, a\right)$ falls between the lines $\left|x+y\right|=4,$ then

$A$ ray of light passing through the point $\left(1, 2\right)$ is reflected on the $x$ -axis at a point $P$ and passes through the point $\left(5, 3\right)$ then the abscissa of a point $P$ is

The equation $4x^2-24xy+11y^2=0$ represents

The graph $y^2+2xy+50\left|x\right|=625$ divides the plane into regions. Then, the area of bounded regions is

A straight line has its extremities on two fixed straight lines and cuts off from them a triangle of constant area $C^2$. Then the locus of the middle point of the line is

A ray of light passing through the point $(1,2)$reflects on the $X$ -axis at point $A$ and the reflected ray passes through the point $(5,3)$ . The coordinate of $A$ is

The tangent of the angle between the lines whose intercepts on the axes are respectively $a,-b$ and $b,-a$, is
