What is the slope of a line that is perpendicular to the line who’s equation is y=4/5x-3
2 answers:
The slope of a line perpendicular to a line with slope x is -. it is the opposite reciprocal. The slope of this line is 4/5. The first step in finding the slope of a line perpendicular to this line is to take the reciprocal of it, which gives us 5/4. The final step is to multiply it by negative 1. This gives us our answer of -5/4.

Answer:
- asymptotes: x = -4, x = 4
- zeros: x = 0
Step-by-step explanation:
The vertical asymptotes of the rational expression are the places where the denominator is zero:
x^2 -16 = 0
(x -4)(x +4) = 0 . . . . . true for x=4, x=-4
x = 4, x = -4 are the equations of the vertical asymptotes

The zeros of a rational expression are the places where the numerator is zero:
4x = 0
x = 0 . . . . . . divide by 4
