if product of slopes = -1 ...it means lines r perpendicular

how would i get the product?
rishavraj
  • rishavraj
like if m1 and m2 are slopes of two lines then if \[m_1 \times m_2 = -1\]

like see \[\frac{ 1 }{ 2 } \times -\frac{ 1 }{ 2 } = -\frac{ 1 }{ 4 }\]
rishavraj
  • rishavraj
so its not perpendicular...bcoz product isn't equal to -1
rishavraj
  • rishavraj
likewise check other options..... if the product is -1 ...then the lines are perpendicular

how would i do 1/3 x 3?
rishavraj
  • rishavraj
\[\frac{ 1 }{ 3 } \times 3 = 1\]
anonymous
  • anonymous
so -1/4 x 4 would be -1?
rishavraj
  • rishavraj
yup :))
