Question

The equation of line parallel to x + y = 7 and passing through the point (1, 2) is ​

Answer 1

hey mate here is ur answer =

As lines are parallel slopes will be equal.

x+y=7

slope of this line=-1

Hence slope of parallel line will be -1

let the line be x+y+c=0

Now (1,2) will satisfy this equation

substitute in it

1+2+c=0

c=-3

hence line is x+y-3=0

x+y=3.

hope it helps .
