State whether the two lines in each of the following are parallel, perpendicular or neither :

Through (3, 15) and (16, 6); through (– 5, 3) and (8, 2)

We have given Coordinates off two line.

Given: (3, 15) and (16, 6) and (– 5, 3) and (8, 2)


To Find: Check whether Given lines are perpendicular to each other or parallel to each other.


Now,


Concept Used: If the slopes of these line are equal the the lines are parallel to each other. Similarly, If the product of the slopes of these two line is – 1, then lines are perpendicular to each other.


The formula used: Slope of a line, m =


Now, The slope of the line whose Coordinates are (3, 15) and (16, 6)




So, m1 =


Now, The slope of the line whose Coordinates are (– 5, 3) and (8, 2)




So, m2 =


Here, m1≠m2 nor m1m2 = – 1


Hence, The lines are neither perpendicular and nor parallel to each other.
