Question

Answer the question please.....

The equation of the line through (1,2),
which makes equal intercepts on the axes,
is
(A) x+y=1 (B) x+y=2
(C) x+y=4 (D) x+y=5​

Answer 1

Answer:

Le the intercepts be a and b.

According to the given condition,

a=b

We know that,

x/a+y/b=1

since the line passe through the coordinate point (1,2)

therefore,1/a+2/b=1

or, 1/a+2/a=1

or, a=3

therefore, the equation of the line,

or, x/3+y/3=1

or,x+y=3

The options given above are not correct
