Its option D. the first is parallel and the rest two will intersect at a point but not at 90 degree. Since, in the fourth one, the lines meet at 90 degree, it is a perpendicular line

The correct option is D.

Important information:

  • Each graph has two lines.

Perpendicular lines:

Two lines are called perpendicular lines if the angle between those lines at the intersection point is 90 degrees.

In option A, the lines are parallel because they have the same direction and slope.

In option B, if we increase the lines, then they can not make a 90-degree angle.

In option C, the lines are not making a 90-degree angle.

In option D, the lines are perpendicular because they are making a 90-degree angle.

Therefore, the correct option is D.
