Question 1104251
What is the line that passes through (1, -5) and is perpendicular to a line with a slope of 1?
--------------------------------------------------------------------------------------------



The perpendicular line wanted will have slope, {{{-1}}}.


{{{(y-(-5))/(x-1)=-1}}}, using formula for slope


{{{y+5=-1(x-1)}}}

{{{y=-x+1-5}}}

{{{highlight(y=-x-4)}}}
