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

Explanation

To find the equation of the line perpendicular to the line given by the equation \( x - 7y + 5 = 0 \) and having an x-intercept of 3, we can follow these steps:

### Step 1: Find the slope of the given line
The equation of the line is in the form \( ax + by + c = 0 \). Here, \( a = 1 \), \( b = -7 \), and \( c = 5 \). The slope \( m_1 \) of the line can be calculated using the formula:

\[ m_1 = -\frac{a}{b} = -\frac{1}{-7} = \frac{1}{7} \]
