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 "5x-2y=-20" into this form"#
#"subtract 5x from both sides"#
#cancel(5x)cancel(-5x)-2y=-5x-20#
#rArr-2y=-5x-20#
#"divide all terms by "-2#
#rArry=5/2x+10larrcolor(blue)"in slope-intercept form"#
#"with slope m "=5/2#
