Line, point in q2, parallel to a horizontal line : Find the general equation of a line through (-2, 1) and parallel to the line y = 2.

Since the given line is horizontal, the parallel line will be horizontal also. Using the horizontal-line form of the equation of the line, we get

y = b. Substituting the coordinates of the required point, we get .

Finally, the equation of the line can be written as y = 1.

In the general form, it becomes y + 1 = 0.
