Answer:

Step-by-step explanation:

x  = 0 represent   y  axis

y = 0  represent  x axis

intersection of x = 0 & y = 0

is origin

pair of linear equation x=0,y=0  

Has unique Solution   at (0 , 0)

Pair of linear Solution is Consistent

as

Lines can be represented by

1.x  + 0 .y  = 0

0.x + 1.y = 0

Hence 1/0 ≠ 0/1   ( and pair of linear equation has unique solution )
