In this why option c is correct. even the first one comes in y=mx form. plz explain.
Dear Student,
Solution)
Now, here x + y = 1 cannot be written in y = mx + c form because line is passing through origin which means c = 0 not 1.
Whereas, x + y = 0 is the form of y = - mx + c
where c = 0 and m = 1
Also, in rest parts, c is not equal to 0 while comparing with y = mx + c.
Hence, c) option is correct.
Regards!
