What is the slope of a line perpendicular to the line whose equation is y=2x + 5?
slope=-1
slope =-1/2
slope=-2

Step-by-step explanation:

General form of equation of line =

Where m is the slope of line

We are given a line

On comparing with general form

m = 2

Let n be the slope of line perpendicular to the line  

The product of the slopes of perpendicular lines is -1

So,

So, Option B is correct

Hence the slope of a line perpendicular to the line whose equation is y=2x + 5 is

6mm^3 or .6cm^3
