Question
Consider the following two lines.
Line 1: Passes through (3,3) and (3,-3)
Line 2: Passes through (-5,2) and (-10,2)
The slope of Line 1 is m=m=
The slope of Line 2 is m=m=
Finally, which of the following is true?
Line 1 is parallel to Line 2
Line 1 is perpendicular to Line 2
Line 1 is neither parallel nor perpendicular to Line 2
Consider the following two lines.
Line 1: Passes through (-9,4) and (1,4)
Line 2: Passes through (-2,-2) and (1,-2)
The slope of Line 1 is m=m=
The slope of Line 2 is m=m=
Finally, which of the following is true?
Line 1 is parallel to Line 2
Line 1 is perpendicular to Line 2
Line 1 is neither parallel nor perpendicular to Line 2
Consider the following two lines.
Line 1: Passes through (-12,4) and (-6,-1)
Line 2: Passes through (0,-2) and (-20,-26)
The slope of Line 1 is m=m=
The slope of Line 2 is m=m=
Finally, which of the following is true?
Line 1 is parallel to Line 2
Line 1 is perpendicular to Line 2
Line 1 is neither parallel nor perpendicular to Line 2
Explanation / Answer
1) line 1 (3,3) and (3,-3)
Line 2: (-5,2) and (-10,2)
finding slope of each line
m1 = ( -3 -3 ) / ( 3 - 3 ) = undefined
m2 = ( 2 - 2 ) / ( -10 + 5) = 0
the two slopes are negative reciprocal of ech other
hence , line 1 is perpendicular to line 2
2nd option is correct
