Line cd passes through (0, 1) and is parallel to x + y = 3. write the standard form of the equation of line cd.
a. x + y = 1
b. x – y = 1
c. x + 1 = y
d. x + y = 11

a.

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 :-

Thus, the equation of line CD =
