Answer:
![\large\boxed{y-8=-0.2(x+10)}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7By-8%3D-0.2%28x%2B10%29%7D)
Step-by-step explanation:
The point-slope form of an equation of a line:
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
m - slope
(x₁, y₁) - point
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
From the table we have the points (-10, 8) and (10, 4). Substitute:
![m=\dfrac{4-8}{10-(-10)}=\dfrac{-4}{20}=-\dfrac{1}{5}=-0.2](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B4-8%7D%7B10-%28-10%29%7D%3D%5Cdfrac%7B-4%7D%7B20%7D%3D-%5Cdfrac%7B1%7D%7B5%7D%3D-0.2)
The equation of a line:
![y-8=-0.2(x-(-10))\\\\y-8=-0.2(x+10)](https://tex.z-dn.net/?f=y-8%3D-0.2%28x-%28-10%29%29%5C%5C%5C%5Cy-8%3D-0.2%28x%2B10%29)
Answer:
After one year Kenny will have $520.
Step-by-step explanation:
It has to be 1900 pounds gold
Answer:
7 million
Step-by-step explanation:
If you use your finger and continue the graph you will get to 7.\.
Horizontal line has a slope of zero because does not rise vertically.
The form that we have to use in this case is y=b because the slope is zero.
So I would say that the answer for this one is
Y=-1
And a vertical line has a undefined slope because it will go up infinitely.
And in this one we have to put the x-intercept.
So I would say that the answer for this one is x=-9
I hope you get it right :D
