Given the equation y=4x-8 what is the slope of a line that is perpendicular to that equation?

Question

How do I do this I don't understand it,(No le entiendo necesito ayuda) I need help

Answer 1

Perpendicular lines have slope that are negative reciprocals of each other

y = 4x - 8 has a slope of 4.

So, a perpendicular line would have a slope of -1/4.
