It would be 30.7% because when you change a decimal to a percent, the decimal point moves 2 places to the right. For a percent to a decimal, move the decimal point 2 places to the left
Answer:
The correct equation is "y=30x+6147". A further explanation is given below.
Step-by-step explanation:
The given values are:
(x1, y1) = (50, 7647)
(x2, y2) = (100, 9147)
As we know,
The slope is,
⇒ ![m=\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
On substituting the given values, we get
⇒ ![=\frac{9147-7642}{100-50}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B9147-7642%7D%7B100-50%7D)
⇒ ![=\frac{1500}{50}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1500%7D%7B50%7D)
⇒ ![=30](https://tex.z-dn.net/?f=%3D30)
Now,
⇒ ![(y-y1)=m(x-x1)](https://tex.z-dn.net/?f=%28y-y1%29%3Dm%28x-x1%29)
On substituting the given values in the above equation, we get
⇒ ![y-7647=30(x-50)](https://tex.z-dn.net/?f=y-7647%3D30%28x-50%29)
⇒ ![y-7647=30x-1500](https://tex.z-dn.net/?f=y-7647%3D30x-1500)
On adding "7647" both sides, we get
⇒ ![y-7647+7647=30x-1500+7647](https://tex.z-dn.net/?f=y-7647%2B7647%3D30x-1500%2B7647)
⇒ ![y=30x+6147](https://tex.z-dn.net/?f=y%3D30x%2B6147)
You could try and multiply I believe so .
