Start at the first point which in this case is (-1,-4). then go up 3 (since thats where the next point is) and over to the right 1 (since thats where the point is lol). since the line is positive, then the answer is 3/1 or 3.
Step-by-step explanation:
Given the Arithmetic sequence

An arithmetic sequence has a constant difference d and is defined by







as


∵ 





∵ 

∵ 
Therefore, the indicated nth partial sum of the arithmetic sequence is 1530.
ANOTHER METHOD
as

n = 30




as

and

so


7 and 1/2+6 and 3/4+7 and 1/3=7+1/2+6+3/4+7+1/3=7+6+7+1/2+3/4+1/3=20+1/2+3/4+1/3
convert bottom nubmer to same (12)
1/2 times 6/6=6/12
3/4 times 3/3=9/12
1/3 times 4/4=4/12
20+6/12+9/12+4/12=20+19/12=20+1+7/12=21+7/12=21 and 7/12
answer is 21 and 7/12 hour or 21.58 hour or 21 hour and 35 minutes
The correct answer is C).
D because 1254.25*4 = 5017.00
