(1,-1)(2,2)
slope = (2 - (-1) / (2 - 1) = 3/1 = 3
y = mx + b
slope(m) = 3
use either of ur points...(2,2)...x = 2 and y = 2
now we sub and find b, the y int
2 = 3(2) + b
2 = 6 + b
2 - 6 = b
-4 = b
so ur equation is : y = 3x - 4
Answer:
14 days
Step-by-step explanation:
18 seconds on day 1
44-18=26
26/2=13 days
Day 1 +13 Additional days=14 days
Yes they are the same because when the negative is distributed into (an+c), the plus sign becomes a negative.
It's B I got it right on my test
