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+4y=8" into this form"#
#"subtract 5x from both sides"#
#cancel(5x)cancel(-5x)+4y=-5x+8#
#rArr4y=-5x+8#
#"divide all terms by 4"#
#rArry=-5/4x+2larrcolor(red)"in slope-intercept form"#
#"with slope m "=-5/4#
