Question

Write the equation of X-axis. Hence, find the point of intersection of the graph of the equation $x+y=4$ with the X-axis.

Answer 1

The equation of $X$ axis is $y=0$

The given equation is $x+y=4$

In order to find the point of intersection of $X$ axis and the given line , put $y=0$ in the given line.

We get $x+0=4$

$\Rightarrow x=4$

Therefore the point of intersection is $(4,0)$
