Question 163652: Directions:Tell whether the line throught the given points are parellel,penpendicular,or niether . Justify your answer .
Line 1: (1,0)(7,4)
Line 2: (7,0)(3,6)
*Now my question is how do you know if it is one of the three lines .(Perpendicular,Parellel,or niether).And How can I justify it ??

You need to calculate the slope for both lines and compare.
Parallel lines have identical slopes
Perpendicular lines have slopes that are negative reciprocals .
If it meets neither of these, then it fits the neither category.

Looks like they're perpendicular because,

parallel lines have the same slope
perpendicular lines have slopes that are negative reciprocals of each other
everything else is neither
slope 1 __ (4-0)/(7-1) __ 4/6 or 2/3
slope 2 __ (6-0)/(3-7) __ 6/(-4) or -3/2
looks like prependicular
