The calculated slope of a line perpendicular to the line with the equation y = -x is B. 1.
What is the slope of the perpendicular line
From the question, we have the following parameters that can be used in our computation:-
y = -x
A linear equation is represented as
y = mx + c
Where
Slope = m
This means that
m = 1
So, the slope of the line y = -x is -1.
Lines are considered perpendicular if their slopes are negative reciprocals of each other.
So, we have
Perpendicular slope = -1/-1
Perpendicular slope = 1
So, the slope of a line perpendicular to y = -x is 1.
