Answer:
37.5% decrease
Step-by-step explanation:
To find a relative percentage you generally follow the rule of part divided by whole.
$100 / $160 = .625 (62.5%)
So $100 is 62.5% of $160
To find the decrease we need to subtract 62.5% from 100%
100 - 62.5 = 37.5
15 and 450 because you divide and multiply until you get the same number
5/1? Im not sure if i am right
Answer:
D. Negative.
Step-by-step explanation:
In truth, when given the graph you don't really need to use the points, but if needed it you would use the formula:
y-y₁=m(x-x₁)
Plug in your information and solve.
-1 - 5 = m (2 - (-1))
-6 = m (3)
-6 = 3m
m = -6 / 3
m = -2
(m = slope)
Also, when shown on the graph =
If the slope is going:
up from left to right: it's positive
down from left to right: it's negative
straight up and down (vertical): it's undefined
straight left to right (horizontal): it's zero.
