Q1 of 112 Page 163

Write the equations of the straight lines parallel to x- axis which are at a distance of 5 units from the x–axis.

Given


The line is ∥ to x axis that means it is a horizontal line at the fixed distance from x axis.


The equation of this line would be of the form y = k where k is some constant.


Here it is given the distance from x axis is 5 units which could be either in positive or negative direction, so the required equation would be


y = 5 or y = –5
