Answer:
5+2y=13 is linear
y=+7 is linear
y-5=2(x-1) is linear
=x+7 idk this is not complete so i cant answer it
x=-4 is linear
HOPE IT HELPED<3 tell me if I am wrong.

Answer:
The parallel line has slope ![\frac{20}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B7%7D)
The perpendicular line has slope ![-\frac{7}{20}](https://tex.z-dn.net/?f=-%5Cfrac%7B7%7D%7B20%7D)
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
In which m is the slope.
Parallel lines:
Parallel lines have the same slope.
Perpendicular lines:
If two lines are perpendicular, the multiplication of their slopes is -1.
In this question:
We have the following line:
![7y = 20(x-3)](https://tex.z-dn.net/?f=7y%20%3D%2020%28x-3%29)
Placing it in the general format
![7y = 20x - 60](https://tex.z-dn.net/?f=7y%20%3D%2020x%20-%2060)
![y = \frac{20x}{7} - \frac{60}{7}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B20x%7D%7B7%7D%20-%20%5Cfrac%7B60%7D%7B7%7D)
So this line has slope ![\frac{20}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B7%7D)
Parallel line:
Same slope, so the parallel line has slope ![\frac{20}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B7%7D)
Perpendicular line:
Multiplication of the slopes is -1. So
![\frac{20m}{7} = -1](https://tex.z-dn.net/?f=%5Cfrac%7B20m%7D%7B7%7D%20%3D%20-1)
![20m = -7](https://tex.z-dn.net/?f=20m%20%3D%20-7)
![m = -\frac{7}{20}](https://tex.z-dn.net/?f=m%20%3D%20-%5Cfrac%7B7%7D%7B20%7D)
The perpendicular line has slope ![-\frac{7}{20}](https://tex.z-dn.net/?f=-%5Cfrac%7B7%7D%7B20%7D)
X = -1 and -1.5 so the 4th answer
Odd degree, negative leading coefficient.
