D. The answer has to be 2,000, eliminating A and C. B doesn't even use the original equation, as well as incorrectly solving the method, so D is the correct answer, even if you don't understand the principles.
Answer:
y = -2x-5
Step-by-step explanation:
So to calculate the slope the equation is y1-y2/x1-x2. We substitute in two points, let's use (-3,1) as x1 and y1, and (1,-7) as x2 and y2. Put those points in the equation and you get -7-1/1-(-3), which is -2. Now you have y=-2x+b
To get b plug in a pair of points to the equations, say (1,-7). -7=-2(1)+b, solve that and you get b=-5.
So y=-2x-5.
Answer:
![slope (m) = -5](https://tex.z-dn.net/?f=%20slope%20%28m%29%20%3D%20-5%20)
Step-by-step explanation:
The slope can be calculated using two points, (2, 60) and (4, 50) as shown below:
, where,
![(2, 60) = (x_1, y_1)](https://tex.z-dn.net/?f=%20%282%2C%2060%29%20%3D%20%28x_1%2C%20y_1%29%20)
![(4, 50) = (x_2, y_2)](https://tex.z-dn.net/?f=%20%284%2C%2050%29%20%3D%20%28x_2%2C%20y_2%29%20)
Plug in the values into the equation
![slope (m) = \frac{50 - 60}{4 - 2}](https://tex.z-dn.net/?f=%20slope%20%28m%29%20%3D%20%5Cfrac%7B50%20-%2060%7D%7B4%20-%202%7D%20)
![slope (m) = \frac{-10}{2}](https://tex.z-dn.net/?f=%20slope%20%28m%29%20%3D%20%5Cfrac%7B-10%7D%7B2%7D%20)
![slope (m) = -5](https://tex.z-dn.net/?f=%20slope%20%28m%29%20%3D%20-5%20)
6th becuase 12-11 would be 1 and up 5 eould be 6
10+4(-8q-4)
14(-8q-4)
then distribute 14 to -8q-4
