Question

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

Answer 1

The answer is 2 bc of the equation

Answer 2

2

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
