Answer:
slope = undefined
Step-by-step explanation:
for two points (x1,y1) (x2, y2)
slope, m = (y2 - y1)/(x2 - x1)
so, for (-1,-10) (-1,-2)
slope = (-2 - (-10))/(-1 -(-1)) = 8/0
slope = undefined
Answer:
The mode for the colors that Santino wore recently is Blue.

To determine the number of cars that will be sold by the year 2020, we will use the equation,
N = (N1)(1 - r)^(t)
where N1 is the starting number of cars, r is the rate of the decrease, and t is the number of years from 2012. Substituting the konwn values,
N = (500)(1 - 0.028)^(8)
N = 398.38
The closest integer to the calculated value is 398. Thus, the answer is 398 cars.
