Select the following lines that would be perpendicular to y = 3x + 1. (select all correct)

question 3 options:

the line passing through points (3,8) and (6,9).

the line passing through points (1,4) and (4,3).

the line passing through points (1,-4) and (4,-5).

the line passing through points (4,3) and (5,6).

The line passing through points (1,4) and (4,3).

The line passing through points (1,-4) and (4,-5).

Step-by-step explanation:

Since the equation is y=3x+1

If it was perpendicular, it means the slope would be the negative reciprocal.

So the slope would be -1/3

9-8/6-3=1/3 (not negative) No

3-4/4-1=-1/3 Yes

-5+4/4-1=-1/3 Yes

6-3/5-4= 3/1 No

answer: the anser is 3
