Q3 of 169 Page 667

Find the equation of a line parallel to the x - axis and having intercept - 3 on the y - axis.

Equation of line parallel to x - axis is given by y = constant, as x - coordinate of every point on the line parallel to y - axis is - 3 i.e. constant.

So, the required equation of line is y = - 3.
