Question

Find the equation of straight line parallel to $Y$axis and passing through point $(1.8,0.9)$

Answer 1

To determine the equation of line:

Given that , the line is parallel to $Y$ axis

The general equation of a line parallel to $Y$axis is

$x=b......\left(1\right)$

Since, the line is passing through point $(1.8,0.9)$, then this point will satisfy the equation

$\Rightarrow b=1.8$

Now put ,$b=1.8$ in equation (1), we get

$x=1.8$

Hence, the equation of straight line parallel to $Y$axis and passing through point $(1.8,0.9)$ is $x-1.8=0$
