Which of the following pairs of lines are perpendicular? select all that apply a y=2/3x+4 and y=2/3x-8 b y=2/3x-8 and y=-3/2x-8 c y=x+3 and y=-x=3 d y=3x+n and y=3x-2 e y=3 and x=4 f y=4/5x-8 and y=-5/4x=3

Hence, B, C and F are pairs of perpendicular line.

Step-by-step explanation:

We have to find the pairs of line that are perpendicular to each other.

Two lines are said to be perpendicular if the product of their slope is -1 that is:

The slope of each line can be calculated with the help of slope intercept form:

1)

2)

3)

4)

5)

6)

Hence, B, C and F are pairs of perpendicular line.

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
