Answer:
![\displaystyle y=-\frac{1}{2}x+1](https://tex.z-dn.net/?f=%5Cdisplaystyle%20y%3D-%5Cfrac%7B1%7D%7B2%7Dx%2B1)
Step-by-step explanation:
The equation of any line in slope-intercept form is:
y=mx+b
Being m the slope and b the y-intercept.
Assume we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
![\displaystyle m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Two points are given: (-6,4) and (-2,2). Calculating the slope:
![\displaystyle m=\frac{2-4}{-2+6}=\frac{-2}{4}=-\frac{1}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20m%3D%5Cfrac%7B2-4%7D%7B-2%2B6%7D%3D%5Cfrac%7B-2%7D%7B4%7D%3D-%5Cfrac%7B1%7D%7B2%7D)
The equation of the line is, so far:
![\displaystyle y=-\frac{1}{2}x+b](https://tex.z-dn.net/?f=%5Cdisplaystyle%20y%3D-%5Cfrac%7B1%7D%7B2%7Dx%2Bb)
To calculate the value of b, we use any of the given points, for example (-6,4):
![\displaystyle 4=-\frac{1}{2}(-6)+b](https://tex.z-dn.net/?f=%5Cdisplaystyle%204%3D-%5Cfrac%7B1%7D%7B2%7D%28-6%29%2Bb)
![\displaystyle 4=3+b](https://tex.z-dn.net/?f=%5Cdisplaystyle%204%3D3%2Bb)
Solving:
b = 1
The equation of the line is:
![\boxed{\displaystyle y=-\frac{1}{2}x+1}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cdisplaystyle%20y%3D-%5Cfrac%7B1%7D%7B2%7Dx%2B1%7D)
We can see none of the choices is correct.
A single appliance has 6 widgets, and a widget has 7 bolts. Therefore, you need to multiply 6 by 7 to find the number of bolts in a single appliance.
6 x 7 = 42
Now that you know the number of bolts in an appliance, you can find the number of bolts in 20 appliances by multiplying 42 by 20.
42 x 20 = 840
Hence, there are 840 bolts in 20 appliances.
two years at 3% = .03*2 = .06
so
.06 times original deposit = 72
so 72/.06
which is
1200
