Question

determine wether mn(line) and rs(line) are perpindicular parrallel or neither
m(-1,3) N(0,5) r(2,1) s(6,-1)

Answer 1

they are neither parallel nor perpindicular

Answer 2

agree wid rajen
slopes are 1/2 & -1/2

Answer 3

there slopes of mn is 2
rs is -1/2

Answer 4

phi i give u a link some1 answer

Answer 5

two lines are parallel if they have identical slopes (though be careful, they could be the same line).
two lines are perpendicular if m1= -1/m2, where m1, m2 are the slopes of line 1 and line 2, respectively.
The slope of line mn is (change in y)/(change in x)
using m(-1,3) N(0,5), we get
\[\frac{5 - 3}{0- -1}=2 \]
the slope of line rs, using r(2,1) s(6,-1), is
\[\frac{-1 -1}{6-2}= \frac{-2}{4}= -\frac{1}{2} \]
Because 2= -1/2, the lines are perpendicular.
