Determine whether the sequence is arithmetic, geometric or neither. Explain. -8, 0, 8, 16 ...

-8 is the answer

Step-by-step explanation:

Opt D.

Step-by-step explanation:

Perpendicular Lines are those with the following condition:

y=a*x+b (1)

y=c*x+d (2)

Where 'a' and 'c' are the respective slope

If These two lines are perpendicular, then

a=- 1/c

Equation (1) in our case is written as y=3x-2, meaning that a=3 and b = -2

Using those principles we have that the slope for our needed line ('c'), has to be c=(-1/3)

Now we most use the given point to find the remaining term of the equation (d) So evaluate it in eq (2) to have this:

7=(-1/3)*(-2)+d

Solving for d results in d= 7-(2/3)

resulting that y=(-1/3)*x +7 -(2/3)

If we re arrange those terms, we have a prettier eq: y-7= (-1/3)*x-(2/3)

which takes you to the opt D the answer you were looking for.
