Question

20. If the linear equation ax + by + c = 0 passes
through (1, 1) then
(1) a + b + c = 0
(2) a - b + c = 0
(3) a = b = c = 1
(4) a = b = c = 0​

Answer 1

Answer:

1)a+b+c=0

this is the correct answer.

Step-by-step explanation:

it is given that the equation passes through(1, 1) , this means that x=1 and y=1.

putting the values of X and y in the equation,

we are only left with a + b + c = 0.

so thats the answer.

hope u find it helpful.
