What is the slope of an equation that is perpendicular to the equation y = 4x + 3 ?

Answer 1

The slope of a perpendicular line is always the reciprocal of the given slope, and then change the sign to its opposite.

example/ y = 2x + 4

perpendicular slope would be: -1/2

Answer 2

Slope of the normal (perpendicular) is -1/4.
