#### Answer:

#### Explanation:

The slope of the given line is (using its standard eqn.

Hence, the slope of reqd. perpendicular line

The rqd. line is thro.

Therefore, using slope-point form of reqd. line, is,

**Otherwise**

A sort-cut method to find the eqn. of a line perpendicular to a given line

In our case, it is given by
