4 SolutionSlope of Line 1 m 4221 2 Slope of Line 2 is 43 G

Solution

Slope of Line 1:

m = (4-2)/(2-1) = 2

Slope of Line 2 is 4/3 (Given)

For the lines to be parallel, they MUST have the same slope, which is not the case.

For them to be perpendicular, product of the slopes should be -1, which is not the case as well. (2*4/3 = 8/3 != -1)

Hence, the two given lines are neither parallel nor perpendicular.
