Ans.....the given equation is ....
x/a + y/b = 1
The point (1, 0) lies on the graph of the above equation, it must satisfy it.
put x = 1 and y = 0 in the above equation.
= 1/a + 0/b = 1
= 1a + 0 = 1
= a = 1
the point (2, 1 ) also lies on the graph of the above equation it must satisfy it.
put x = 2 and y = 1, in the above equation.
2/a + 1/b = 1
= 2/1 + 1/b = 1 [ as a = 1 ]
= 1/b = 1 − 2 = −1
= b = − 1
