Given is an Isosceles triangle LMN with vertices L(0, 1), M(3, 5), and N(6,1).
It says to find the slope of the side LN.
We know the formula for slope of any two points is given as follows :-
[tex]Slope = \frac{y_{2} -y_{1} }{x_{2} -x_{1} } \\\\
Slope \;of \;L(0,1) \;and \;N(6,1) \\\\
Slope = \frac{1-1}{6-0} \\\\
Slope = \frac{0}{6} \\\\
Slope = 0 [/tex]
Slope of LN = 0 means " LN is a horizontal line".
