Respuesta :
perpendicular lines have negative reciprocal slopes. So if 1 slope has a slope of 1/2, then its perpendicular line has a slope of -2/1 or just -2
Answer: -2
Step-by-step explanation:
Given : The slope of a line is [tex]\dfrac{1}{2}[/tex].
We know that the product of two perpendicular lines is -1.
Let m be the slope of line that is perpendicular to given line.
Then,we have :-
[tex]m\times\dfrac{1}{2}=-1\\\\\Rightarrow\ m=-2[/tex]
Hence, the slope of a line that is perpendicular to this line =-2
