Answer:
m = (y2 - y1) / (x2 - x1) | * (x2 - x1)
m * (x2 - x1) = y2 - y1 | + y1
m * (x2 - x1) + y1 = y2
Answer D is correct.
Answer:
Well.
Step-by-step explanation:
If its 28 km for hour. A quarter of 28 is 7 so then 28+7=35 km.
To my best knowledge the slop that is increased is number 3 it is moving up in a slop and it is sloped.
Answer:
y = 40
Step-by-step explanation:
For #7, we are told that y = 10 when x = 2
We are also told that 'y varies directly as x'. That means there is some constant number, k, so that
Formula --> y = kx
Since y=10 and x= 2, we substitute those numbers into the formula.
We get 10 = k × 2.
So k has to be 5, right?
k = 5
So what is y when x = 8?
Use the formula.
y=kx ---> That gives us y = k × 8. But we know k is 5.
So y = 5 × 8 = 40
y = 40
