Answer:
x+y=2
Step-by-step explanation:
let the line cut the X axis at A (x1, y1) ,cuts Y axis at B(x2, y2) mid point is (1,1)
a line cuts x axis then y1=0,cuts y axis at B then x2=0
as mid point is (1,1) then x1=2(1)=2,y2=2(1)=2
therefore x intercept is 2,y intercept is 2
line equation is x/a+y/b=1 where a is x intercept, b is y intercept so line equation is
x/2+y/2=1
(x+y)/2=1
x+y=1(2)
x+y=2.
THEREFORE YOUR ANSWER IS x+y=2.Option d is correct.
I hope you are satisfied by my answer.
