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#
#"the equation of a line in "color(blue)"slope-intercept form"# is.
#•color(white)(x)y=mx+b#
#"where m is the slope and b the y-intercept"#
#y=2x-3" is in this form with "m=2#
#rArrm_(color(red)"perpendicular")=-1/2#
#rArry=-1/2x-7larrcolor(blue)"in slope-intercept form"#
