The perpendicular from the origin to the line `y=m x+c` meets it at the point (-1,2). Find the values of `m\ and\ c dot`

Explanation

The given equation of line is `y=mx+c.`

It is given that the perpendicular from the origin meets the given line at` (−1,2)`.


Therefore, the line joining the points`( 0,0)` and `(−1,2) `is perpendicular to the given line.


slope of the line joining (0,0) and (−1,2) is `=(−2​)/(1)=−2`

The slope of the given line is m.

`mxx−2=−1` [the two lines are perpendicular]
