<span>If Marta's handler uses a graph to track the number of gallons of formula y the calf drinks in x hours then the relationship between x and y is linear and it is proportional. This is because the formula enables the calf to drink more and grow more.</span>
0.13 is your answer you are looking for.
Answer: 6
Step-by-step explanation:it iss what it iss
Answer:
I believe it is 32
Step-by-step explanation:
I think this because in your equation it says (y=32x) which 32 will mean how much he is charging for each skateboard, x will be how many he sells, and y would be how much he makes from selling them. So if he sold 2 skateboards you would do.. 32 x 2 which equals 64 soo that would be (64=32x2) so it is 32
Equation of line passing through two points
=![\frac {y-y_{1}}{x-x_{1}}=\frac{y_{2} - y_{1}}{ x_{2}-x_{1}}](https://tex.z-dn.net/?f=%5Cfrac%20%7By-y_%7B1%7D%7D%7Bx-x_%7B1%7D%7D%3D%5Cfrac%7By_%7B2%7D%20-%20y_%7B1%7D%7D%7B%20x_%7B2%7D-x_%7B1%7D%7D)
Now , we will find first equation of line which passes through (-4,4) and (-2,0) is :
![\frac{y-4}{x+4}= \frac{0-4}{-2+4}\\\\\frac{y-4}{x+4}= \frac{-4}{2}\\\\y-4 = -2 x -8\\\\y +2 x +4=0](https://tex.z-dn.net/?f=%5Cfrac%7By-4%7D%7Bx%2B4%7D%3D%20%5Cfrac%7B0-4%7D%7B-2%2B4%7D%5C%5C%5C%5C%5Cfrac%7By-4%7D%7Bx%2B4%7D%3D%20%5Cfrac%7B-4%7D%7B2%7D%5C%5C%5C%5Cy-4%20%3D%20-2%20x%20-8%5C%5C%5C%5Cy%20%2B2%20x%20%2B4%3D0)
The Second line which passes through (0,-4) and (2,-8) is :
![\frac{y+4}{x-0}= \frac{-8+4}{2-0}\\\\\frac{y+4}{x}= \frac{-4}{2}\\\\y+4 = -2 x \\\\y +2 x +4=0](https://tex.z-dn.net/?f=%5Cfrac%7By%2B4%7D%7Bx-0%7D%3D%20%5Cfrac%7B-8%2B4%7D%7B2-0%7D%5C%5C%5C%5C%5Cfrac%7By%2B4%7D%7Bx%7D%3D%20%5Cfrac%7B-4%7D%7B2%7D%5C%5C%5C%5Cy%2B4%20%3D%20-2%20x%20%5C%5C%5C%5Cy%20%2B2%20x%20%2B4%3D0)
So equation of line passing through (-4,4) , (-2,0) ,(0,-4) and (2,-8) is :(All points are collinear, so there will be unique line passing through these four points.)
2 x + y + 4=0
