Answer:
slope =-1
Step-by-step explanation:
We are given a line represented by the equation y =-x+k
where k is any real number
We have to find the slope of the line.
We know that a line is represented in slope intercept form as
y=mx+b
where m is the slope and b is the y intercept
we have y =-x+k so slope = -1 and y intercept = k
Hence answer is slope =-1
