Answer:
1 and −1
Step-by-step explanation:
the equation of a line in slope-intercept form is.
∙xy=mx+b
where m is the slope and b the y-intercept
y=x+5 is in this form
with slope =m=1
∙ Parallel lines have equal slopes
⇒slope of line parallel to y=x+5 is m=1
Given a line with slope m then the slope of a line
perpendicular to it is
∙xmperpendicular=−1m
⇒mperpendicular=−11=−1
Have a great day
