Answer: a. ![x+y=1](https://tex.z-dn.net/?f=x%2By%3D1)
Step-by-step explanation:
Given: Line CD passes through (0, 1) and is parallel to
.
We know that if two line are parallel then they have equal slopes.
Thus, the slope of line = slope of line
.
when we compare this to the standard linear equation
.we get
.
Hence, slope of CD (m)= -1
Now, the equation of line CD passing through (0,1) is given by :-
![(y-1)=m(x-0)\\\Rightarrow(y-1)=(-1)x\\\Rightarrow x+y=1](https://tex.z-dn.net/?f=%28y-1%29%3Dm%28x-0%29%5C%5C%5CRightarrow%28y-1%29%3D%28-1%29x%5C%5C%5CRightarrow%20x%2By%3D1)
Thus, the equation of line CD = ![x+y=1](https://tex.z-dn.net/?f=x%2By%3D1)
