Answer:
Step-by-step explanation:
hello : 
let :    Z1 = 2-4i       Z2 = 6+i  
 the distance between Z1  and  Z2 is : 
/Z2 - Z1 / = /(6+i)-(2-4i)/ =/4+5i/ = √(4²+5²) =√41

The answer :
4/5
Step-by-step explanation:
4x-5y=0  
subtract 4x on both the sides  
4x-4x-5y = 0-4x  
-5y = -4x
divide by -5 on both the sides  
-5y/-5 = -4x/-5
y =( 4/5 )x
