Point-slope:
y-y1= m(x-x1)
Plug in what you know.
y1= 1 and x1= -8
y-1= 2/5(x-(-8)
y-1= 2/5(x+8)
Distribute.
y-1=.4x+ 3.2 <- that is the final answer
I hope this helps!

Answer:
30 red cars
Step-by-step explanation:
3x + 5x = 240
8x = 240
x = 30
red:blue = 3:5
30
Assuming a standard normal distribution, the positive value of interest will be that corresponding to the 50 + 36/2 = 68th percentile. A suitable probability calculator will give that value as 0.46770.
The values that are within ±0.46770 standard deviations from the mean will have a probability of 0.36.
Answer:
It approximately dropped 0.027777 per hour.
Step-by-step explanation:
First, we calculate the decrease.
Decrease = 11/40 = 0.275
Then, we calculate the time interval.
From 10 pm to 7:54 hours will be 9.54 hours
Time interval= (9 + 54/60) hours
Time interval=9.9 hours
Finally, we calculate how much it dropped each hour
0.275/9.9 ≈ 0.027777
So it approximately dropped 0.027777 per hour.
