2. x - 4y = 20

Step-by-step explanation:

1. Reason 2: Multiplying -2 with the bracket term in the left-hand side,

This is the Distributive property of multiplication.

Reason 3: Addition of 4x with both sides.

Reason 4: Subtracting 14 from both sides.

Reason 5: Dividing both sides by -2. (Answer)

2.  

The equations of straight lines 4x + y = 3 and x - 4y = c (1) are always perpendicular to each other for any constant value of c.

{Since, the product of slopes of two perpendicular straight lines is -1}

Now, this equation (1) passes through the point (-4,-6) and it will satisfy the equation.

Hence, - 4 - 4(- 6) = c, ⇒ c = 20

Therefore, x - 4y = 20 is the equation of the perpendicular straight line. (Answer)
