Answer:
6825
Step-by-step explanation:
From the equation, the series is a geometric series, such that
a = 5
r = 4
n = 6
sum of a geometric series is a(r^n - 1)/(r - 1)
therefore,
sum of the series is 5 x (4^6 - 1) / (4 - 1)
= 5 x (4096 - 1) / 3
= 5 x 4095 / 3
= 6825

D is the correct answer.
First find the slope: 2-5/8-9=3 So slope is 3
(y-y1)=m(x-x1) is the point slope formula
plug in the numbers (y-5) = 3(x-9)
y-5 = 3x-27
y=3x-22
