Answer:

#"slope "=2," y-intercept "=-1#

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#
