Algebra-1

To determine which line is perpendicular to y = 15x + 8, we need to find the negative reciprocal of the slope of this line.

Finding the Slope of y = 15x + 8

The slope of this line is 15.

 

Negative Reciprocal

The negative reciprocal of 15 is .

 

Checking Each Option

A.  

Slope: 

This is the negative reciprocal of 15, so this line is perpendicular.

 

B. 

Slope: 15

This is the same as the original slope, so this line is not perpendicular.

 

C.
