On solving the provided question, we got to know that - they are perpendicular, they are perpendicular and they are intersecting lines
what are perpendicular lines?
A straight line that intersects another straight line at a 90° angle is said to be perpendicular. A little square is placed in the middle of two vertical lines to represent a 90° angle, often known as a right angle, as illustrated. The two straight lines in this instance are perpendicular to one another since they connect at a right angle.
1) For this case, we have to define perpendicular lines:
[tex]m1 * m2 = -1[/tex]
[tex]m1 = 1/5\\m2 = -5\\so, m1*m2 = -1\\[/tex]
they are perpendicular
2) they are perpendicular
3) they are intersecting lines
