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

the answer choices are

-2

-1/2

1/2

2

2

Step-by-step explanation:

as you can see the slope of the line y = - 1/2x + 5 is - 1/2

the slope m of any line perpendicular to it should verify : - 1/2*m = - 1

-1/2*m = - 1

→ multiply both sides by - 2

m = 2

The answer is 2 bc of the equation
