Firstly, we will find slope of the given lne
we can select any two points from the graph
(-4,-5) and (4,-1)
so, x1=-4 , y1=-5 m x2=4 , y2=-1
now, we can use formula
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
now, we can plug values
![m=\frac{-1+5}{4+4}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-1%2B5%7D%7B4%2B4%7D)
![m=\frac{1}{2}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B1%7D%7B2%7D)
(B)
we are given
line parallel to the nline shown
and we know that
slope of two parallel lines are always equal
so, slope will also be
![m=\frac{1}{2}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B1%7D%7B2%7D)
we have point as (3,4)
now, we can use point slope form of line
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
we can plug values
![y-4=\frac{1}{2}(x-3)](https://tex.z-dn.net/?f=y-4%3D%5Cfrac%7B1%7D%7B2%7D%28x-3%29)
we get
![y=\frac{1}{2}x+\frac{5}{2}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B2%7Dx%2B%5Cfrac%7B5%7D%7B2%7D)
(D)
we have point as (-3, 2)
and we know that
slope of perpendicular line is -1/m
so,
![m_p=-2](https://tex.z-dn.net/?f=m_p%3D-2)
now, we can use point slope form of line
![y-2=-2(x+3)](https://tex.z-dn.net/?f=y-2%3D-2%28x%2B3%29)
we get

Answer:
-25/8 I think
Step-by-step explanation:
You need to multiply the amount by the tax
9-2=7
3+4=7
9 plus 2 equals 7 and 3 plus 4 also equals 7.
