Answer:
The third option, y=(-1/3)x-7
Step-by-step explanation:
To find a line perpendicular to an equation, you find the negative reciprocal of the slope. For instance, if you have an equation y=4x+5, the negative reciprocal is y=(-1/4)x+5. That is the equation to find a line perpendicular to this. 
If you want to find a line parallel to the equation y=4x+5, all you have to do is come up with another equation that has the same slope. So, y=4x+8 would be a line parallel to the equation y=4x+5.

Answer:
A
Step-by-step explanation:
The x- coordinate of each point ( the domain ) maps to exactly 1 unique y- coordinate ( the range). 
This means the situation given represents a function → A
 
        
             
        
        
        
Answer:
You plug in the values of x's and then minus 1 and you get your y
