Find the equation of a line parallel to the x - axis at a distance of
(i) 4 units above it
(ii) 5 units below it
(i) Equation of line parallel to x - axis is given by y = constant, as the y - coordinate of every point on the line parallel to x - axis is 4,i.e. constant. Now the point lies above x - axis means in positive direction of y - axis,
So, the equation of line is given as y = 4.
(ii) Equation of line parallel to x - axis is given by y = constant, as the y - coordinate of every point on the line parallel to x - axis is - 5 i.e. constant. Now the point lies below x - axis means in negative direction of y - axis,
So, the equation of line is given as y = - 5.
