Answer:
This is a function, because for every x-value, there is exactly one y-value.
The domain is: {-5, -4, -3, -2}, and the range is {-2, -1, 0}
Let me know if this helps!
 
        
             
        
        
        
So, 6/7*56/1
56*6/7
336/7
the answer is 48

Answer:
Its perpendicular
Step-by-step explanation:
You can solve the equation to get x=-2.5 and y = -7.5 so they intersect there, but they intersect at 90 degrees so its perpendicular.
