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-y=1" into this form"#
#"subtract "2x" from both sides"#
#cancel(2x)cancel(-2x)-y=-2x+1#
#rArr-y=-2x+1larrcolor(blue)"multiply through by "-1#
#rArry=2x-1larrcolor(blue)"in slope-intercept form"#
#"with slope "=2" and y-intercept "=-1#
