Answer:
A
Step-by-step explanation:
5*10^3=5*1000=5000
5*10^4=5*10000=50000
The answer to your problem is A due to the slope of your line being -1/3x.
You can find this slope by picking two points on your graph [i.e. (-1,3) and (0,0)].
Find the difference between the two points, which is a one for the x value and a three for the y values. Now you have a slope of 1/3.
But wait! The slope is downwards, therefore a negative must be applied to your slope.
This provides you with a slope of -1/3x, therefore:
y = -1/3x
Answer:
I believe it is because it does not start at 0
Calculate for 3 days: 2,400 x 3 = 7,200
Calculate 1 day per hour: 2,400 ÷ 24 = 100
Calculate for 6 hours: 100 x 6 = 600
7,200 + 600 = 7,800 watt-hours
I think is should be (5,0)
