Perpendicular lines have slopes that are negative reciprocals. First, we write the given equation in slope intercept form by solving for y:
x−y=5
x−5=y
or
y=x-5
So, the slope of the given line is 1 which means that the slope of the line perpendicular to it is:
\(\displaystyle-{\left(\frac{{1}}{{1}}\right)}=-{1}\)
0
