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

Answer»

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 .
