Explanation:
#"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"#
#"rearrange "-2x+3y=21" into this form"#
#"add 2x to both sides"#
#cancel(-2x)cancel(+2x)+3y=2x+21#
#rArr3y=2x+21#
#"divide all terms by 3"#
#rArry=2/3x+7larrcolor(blue)"in slope-intercept form"#
#"with slope m "=2/3" and y-intercept "=7#
