YOU HAVE TO FIND THE SLOPE m
The formula to find the slope is m=(y₂-y₁)/(x₂-x₁)
Since we have the coordinate of each point, then we can calculate the slope m
7) (-6-3)/(2+4) = -9/6 =-3/2 (slope negative so the function falls
8) (-1-1)/(7-7) = -2/0 (tan ---> ∞ ) VERTICAL
9) (-2+2)/(5-3) = 0/2 = 0 slope = 0 ===> Horizontal
The DJs unit rate is 5 songs for every 1 commercial.
I found this by dividing both the commercials and the songs by their greatest common factor, or 2.
1000 milliliters are in a liter.
Y=k/x
1.6=k/0.5
K=0.8
Y=0.8/x
3.2=0.8/x
X=0.8/3.2
X=0.25
Hope this helps
It would take around 75.75 minutes for it to fully charger from 0%
