Question

Pls help and thanks

Answer 1

A. -10

Explanation:

Hi there!

We are given that the equation of line m is
`y=(1)/(10)x`, and we want to find the slope of the line perpendicular to m

Perpendicular lines have slopes that multiply to get the result of -1

So let's find the slope of line m

The equation is written in the form y=mx+b, where m is the slope, and b is the y intercept

As
`(1)/(10)` is in the place of where the slope should be,
`(1)/(10)` is the slope

Now find the slope of the perpendicular line with this formula:

`m_1*m_2=-1`

`m_1=(1)/(10)`

In that case,

`(1)/(10)*m_2=-1`

Multiply both sides by 10

`m_2=-10`

So the slope of the perpendicular line is -10, or A

Hope this helps!
