Explanation:
#"rearrange " 2x-3y-5=0" into " color(blue)"slope-intercept form"#
#• y=mx+b# where m represents the slope and b, the y-intercept.
#rArr-3y=-2x+5# divide all terms by - 3
#(cancel(-3) y)/cancel(-3)=(-2)/(-3)x+5/(-3)#
#rArry=2/3x-5/3larrcolor(red)" in slope-intercept form"#
#rArr"slope "=m=2/3# The slope of a perpendicular line is the
#color(blue)"negative reciprocal"" of " m#
#rArrm_("perpendicular")=-1/m=-1/(2/3)=-1xx3/2=-3/2#
