Answer:
Explanation:
Dang, they made this a little harder. Now we need to actually calculate a slope. Good thing is, it's relatively easy. Slope is basically the rate of change, or the rise of the function over the run, which is shown as:
Δy/Δx
We can use two points to find the slope. I will use (2,795) and (4,1525)
(y1 - y2) / (x2 - x1)
(1525 - 795) / (4 - 2)
730 / 2
365
This is our slope, 365x.
Now we need the y-intercept, which is where the line hits the y-axis. It seems to be at 100, so the new equation is:
y = 365x + 100
If we want to know how many followers Lauren will have in 2018, we just use 7 for x years after 2011, since 2018 is 7 after 2011.
y = 365(7) + 100
y = 2555 + 100
y = 2655
Lauren has 2655 followers in 2018.
Station 6-
The x-intercept tells us when the depth below the sea level is 0 feet.
The y-intercept tells us the starting depth when the time is 0.
The meaning of the slope being -10x is that the depth below the sea level decreases 10 feet per minute. Hope this helps, and sorry for seeing this late!
