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

−2

2

−1/2

Step-by-step explanation:

Hi there!

In the given equation , the slope of the line is 2.

Perpendicular lines always have slopes that are negative reciprocals, like negative "flipped" fractions.

Example: The negative reciprocal of (which is the same as 3) is .

Example 2: The negative reciprocal of is .

Using this logic, the negative reciprocal of 2, or , is . Therefore, the slope of a line perpendicular to the line is .

I hope this helps!
