Explanation:
Hello
to find the slope we must to know that the slope of a line is a number that measures its "steepness", usually denoted by the letter m. It is the change in y for a unit change in x along the line

Let
m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\\
L ⇒ P1 (0,1)

N⇒ P2(6,1)


m=0
which means that the line LN is horizontal
