Step-by-step explanation:
45 minutes.
3 x
--- ----
4 60
you multiply 60 and 3.
you get 180, then you divide by 4 and get 45 minutes.
Percent change = change/original * 100
(2.65 - 2.30)/ 2.65 * 100
.35/2.65 * 100
13.2 % decrease
-13.2% if you need to write is as a negative
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (9, 2) and (x₂, y₂ ) = (9, - 5)
m =
= 
Since division by zero is undefined then the slope is undefined.
This indicates that the line is vertical.
