Answer:
True
Step-by-step explanation:
It passes the vertical line test, meaning you can draw a vertical line anywhere on the graph and it will only intersect at one point
this means that for every input (x value) there is only one output (y value)
 
        
             
        
        
        
P = kq/r
5 = k*1/2
k = 2*5 = 10
p = 5*10/50 = 1
P is 1.
