Question

Write the equation of a line parallel to x- axis and at a distance of 3 units from it. How many such

lines are there?​

Answer 1

Answer:

Hence, the equation of line parallel to x-axis which is at a distance of 2 units above it is y – 2 = 0. Hence, the equation of line parallel to x-axis which is at a distance of 3 units below it is y + 3 = 0.
