Question

Write the equation of the line: parallel to the X-axis and at a distance of 4 units from the point (−2, 3).

Answer 1

Equation of a line parallel to the X-axis is of the form y = k (k > 0 or k < 0).

Since, the line is at a distance of 4 units from the point (−2, 3).

∴ k = 3 + 4 = 7 or k = 3 − 4 = −1

∴ The equation of the required line is y = 7 or y = −1.
