Answer:
<em><u>Lines are perpendicular to each other .</u></em>
Step-by-step explanation:
Standard equation  of line is : y = mx + c, Where m represents the slope
Given Equations :


Two lines are parallel if the slope of the lines are same.
Two line are perpendicular if the product of the slope = - 1
Clearly slopes are not equal , therefore the lines are not parallel.
            product of the slope is - 1, therefore the lines are perpendicular.  
                                 
 
        
             
        
        
        
Answer:
4
Step-by-step explanation:
AB = ![\sqrt{[(4-(-4)]^{2} - [1-(-3)]^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5B%284-%28-4%29%5D%5E%7B2%7D%20-%20%5B1-%28-3%29%5D%5E%7B2%7D%20%7D) = 4
 = 4
 
        
             
        
        
        
4 and 8 would be the anwser because 4 x 2 = 8 and then 8x1=8
