Answer: The infinite geometric series converges to 38.4
====================================================
Explanation:
Divide each term by its previous term
term2/term1 = 9.6/19.2 = 0.5
term3/term2 = 4.8/9.6 = 0.5
The common ratio is r = 0.5
Since -1 < r < 1 is true, this means the infinite geometric series converges.
It converges to...
S = a/(1-r)
S = 19.2/(1-0.5)
S = 38.4
Answer:
y = mx + b
m = (-7 - -5) / (5 - 4) = -2
y = -2x + b
Use either point to find b
Using (4, -5):
-5 = (-2)(4) + b
-5 = -8 + b
b = 3
y = -2x + 3
