Question

18. Referring to question 17, which equation could be thatwhich is perpendicular to the equation given?

Answer 1

The slope of one line perpendicular to another is the negative inverse

`m_p=-(1)/(m)`

For the equation

`y=2x-5`

The slope of the line is

`m=2`

So the slope of a perpendicular line will be:

`m_p=-(1)/(2)`

So the anwer is A

`y=-(1)/(2)x+2`
