Question

Lines J and k are perpendicular. The slope of line k is 3. Which equation is true?

A) 3• slope of j=-1
B) -3• slope of j=-1
C) 1/3• slope of j=-1
D) -1/3• slope of j=-1

Answer 1

the answer is A.
Multiplying perpendicular slopes results in -1. Multiply the slope of j by the slope of k(3) to get -1.

Answer 2

Answer:

the answer must be A. 3. slope of j=1
