You can see that points A and C have same oordinate (y axis) . i. e. 1.
Since point B lies on the same line, its oordinate b will also be equal to 1.
And a-b=1
Putting value of b as 1, we get,
a-1=1
Thus a=2
Thus a=2 and b=1 coordinates of point B are (2,1). Hope you got it

wow genius
but how you need to solve with formula or else they wnot give marks
no buddy, maths is not about formula... it is about how you apply your mind... if your teacher argues on such silly things, you must report it.
