Write the equation of the line satisfying the given condition.

Perpendicular to y = 4x + 2 and passing through the point (0, -4)
(Hint: Slopes of non-vertical perpendicular lines are negative reciprocal of each other.)

The equation of the new line can be stated as

y = (-1/4)x -4

without doing any calculations.
y = 4x + 2. (0,-4).
m = 4.

m2 = -1/4.

y = (-1/4)*0 + b = -4,
b = -4.
Eq: y = (-1/4)x - 4.
Why doesn it nee
Why does it need to be -4?
