Explanation:
#"given a line with slope m then the slope of a line"#
#"perpendicular to it is "#
#•color(white)(x)m_(color(red)"perpendicular")=-1/m#
#"rearrange "x-y=16" into "color(blue)"slope-intercept form"#
#•color(white)(x)y=mx+b#
#"where m is the slope and b the y-intercept"#
#x-y=16rArry=x-16#
#rArrm=1#
#rArrm_(color(red)"perpendicular")=-1/1=-1#
