If the angle between the two lines represented by `2x^2+5x y+3y^2+6x+7y+4=0` is `tan^(-1)(m),` then find the value of `mdot`

Options

A. (a) `1/5`
B. (b) `1 `
C. (c) `7/5`
D. (d) `7`

Explanation

To solve the problem, we need to find the value of \( m \) given the equation of the pair of lines represented by:

\[ 2x^2 + 5xy + 3y^2 + 6x + 7y + 4 = 0 \]

### Step 1: Identify the coefficients
The general form of the equation of a pair of lines is given by:
