Find equation of the line perpendicular to the line `x - 7y + 5 = 0`and having x intercept 3.

Explanation

Equation of given line,

`x-7y+5 = 0`

`-7y =-x-5`

`y = 1/7x+5/7`

Comparing this equation with,
`y = mx+c`

We get, Slope of the line, `m = 1/7`

Now, if slope of required line is `m_1`, then,
