Explanation:
#"given a line with slope m then the slope of a line"#
#"perpendicular to it is"#
#m_(color(red)"perpendicular")=-1/m#
#"the equation of a line in "color(blue)"point-slope form"# is.
#•color(white)(x)y=mx+b#
#"where m is the slope and b the y-intercept"#
#"rearrange "-2y=3x+7" into this form"#
#"divide all terms by "-2#
#rArry=-3/2x-7/2to"with "m=-3/2#
#rArrm_(color(red)"perpendicular")=-1/(-3/2)=2/3#
