Question

4. Seg AB is parallel to the X-axis and the coordinates of point A are (1, 3), then the coordinates
of point B are
(A) (3, 1)
(B) (5, 3)
(C) (3, 0)
(D) (1, -3)​

Answer 1

Answer:

Let the coordinate of point B be (x, y). Slope of AB = y − 3 x − 1 = slope of y-axis Slope of y-axis is not defined as the denominator is 0 so, the denominator of y − 3 x − 1 will also be 0. with here is only 1 option that (D). Hence, the correct answer is (1,–3) .
