Question 11 Mark
Write the equation of the line parallel to the X-axis at a distance of 5 units from it and below the X-axis.
Answer
The equation of a line parallel to the X-axis is y = b.
Since, the line is at a distance of 5 units below the X-axis.
∴ b = -5
∴ y = -5 is the equation of the required line.
