For the equation -4y=8x what is the constant of variation
dybincka [34]
Direct Variation. Since k<span> is constant (the same for every point), we can find </span>k<span> when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x , and y = 6 when x = 2 , the constant of variation is </span>k<span> = = 3 . Thus, the equation describing this direct variation is y = 3x .</span>

A farmer has chickens and cows. You ask the farmer how many chickens he has, and how many cows he has. The farmer has 28 healthy
crimeas [40]
Set the number of chickens as x and number of cows as <span>y
</span>so the farmer has total 28 animals
so x+y=28 
you know that since the animals are healthy
chickens will have 2 legs    and
cows will have 4 legs
the total number of legs are 64
so 2x+4y=64
since you want to find the number of cows 
so from the first equation <span>x+y=28
</span>we will get another equation <span>x=28-y
</span>then plug into <span>2x+4y=64
2(28-y)+4y=64
56-2y+4y=64
56+2y=64
-56      -56
2y=8
y=4
</span>

PLEASE HELP ASAP WILL GIVE BRAINLIEST! :) <br><br><br>sorry for the quality.​
ss7ja [257]

Answer:

y=3x—1

Step-by-step explanation:

The line contains point (2,5)

so if we put x=2 in the equation, that'll give us y=5

only option that contains point (2,5) is:

y = 3x  - 1 \\ (5) = 3(2) - 1 \\ 5 = 5 \: true
