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 "8x+5y=40" into this form"#
#"subtract "8x" from both sides"#
#rArr5y=-8x+40#
#"divide all terms by 5"#
#rArry=-8/5x+8larrcolor(blue)"in slope-intercept form"#
#"with slope "=-8/5#
