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 "3x-y=-2" into this form"#
#"add "y" to both sides"#
#3xcancel(-y)cancel(+y)=y-2#
#rArr3x=y-2#
#"add 2 to both sides"#
#rArr3x+2=ylarrcolor(blue)"in slope-intercept form"#
#"with slope "=3" and y-intercept "=2#
