Answer:
y=(-4/1)x-5
Step-by-step explanation:
You need to find the slope of the line and the y intercept, you can do this by plotting the points into a graph and figuring it out that way, or you can use the equations y2-y1/x2-x1 (for slope) and y=(*the slope from the other equation*)x+b. For both equations plug in a corresponding x and y coordinate given on the list (y1 and y2 would be consecutive coordinates, so 1 and 2, and same for x1 and x1, so -9 and -13). You should get (-4/1) for the slope, and when you plug that into the other equation you should get 5. Lastly you plug all these numbers into y=mx+b, and you get your answer.
Hope this helps :)
Given:
The equation in point slope form is
![y-4=\dfrac{3}{4}(x+8)](https://tex.z-dn.net/?f=y-4%3D%5Cdfrac%7B3%7D%7B4%7D%28x%2B8%29)
To find:
The equation of the same line in standard form.
Solution:
Standard form of a line is
![Ax+By=C](https://tex.z-dn.net/?f=Ax%2BBy%3DC)
We have,
![y-4=\dfrac{3}{4}(x+8)](https://tex.z-dn.net/?f=y-4%3D%5Cdfrac%7B3%7D%7B4%7D%28x%2B8%29)
Multiply both sides by 4.
![4(y-4)=3(x+8)](https://tex.z-dn.net/?f=4%28y-4%29%3D3%28x%2B8%29)
![4y-16=3x+24](https://tex.z-dn.net/?f=4y-16%3D3x%2B24)
Isolate variable terms.
![-3x+4y=16+24](https://tex.z-dn.net/?f=-3x%2B4y%3D16%2B24)
![-3x+4y=40](https://tex.z-dn.net/?f=-3x%2B4y%3D40)
Multiply both sides by -1.
![3x-4y=-40](https://tex.z-dn.net/?f=3x-4y%3D-40)
Therefore, the correct option is B.
Answer:
5x-y +5 =0
Step-by-step explanation:
y – 5x = 5
5x-y +5 =0
Answer:
9r
Step-by-step explanation:
1.5r - 3r + 10.5r
10.5r + 1.5r = 12r
12r - 3r = 9r
Final Answer = 9r
Step-by-step explanation:
if he has 3 plants and each plant got 5/9 gallons of water, you simply multiply 5 from the 5/9 and 3 which is 15 then your answer will be 15/9 but its up to you to simplify it. hope this helps!
