Question

What is the slope of a line that is perpendicular to the line y = 8x + 5?

Answer 1

perpendicular lines, slope is opposite and reciprocal
y = 8x + 5 has slope = 8
so perpendicular line slope = -1/8

answer
-1/8

Answer 2

Answer:
`(1)/(8)`

Explanation:

The given equation of a line :
`y = 8x + 5`

We know that general Slope-intercept form of equation is given by :-

`y=mx+c`, where m is the slope of the line.

When we compare the given equation the general slope intercept form of equation , we get

Slope of line = 8

We know that the product of slopes of two perpendicular line is -1.

Let m be the slope of line that is perpendicular to the line
`y = 8x + 5`, then we have

`-8* m=-1\\\\\Rightarrow\ m=(1)/(8)`
