Answer:
y = -1/3x + 4
Step-by-step explanation:
y = 3x +5
current slope m is 3, perpendicular is opposite inverse which is -1/3
Passing through (6,2):
y = mx + b
2 = -1/3(6) + b
2 = -2 + b
b = 4
Use the perpendicular m = -1/3 and b = 4 to form equation of line:
y = mx + b
y = -1/3x + 4
The arithmetic sequence with the given condition is determined recursively by

So we have



and so on with the general pattern

This means the 72nd term in the sequence is

so the answer is B.
A= 3.1 and b= 2.5 hope this helps
