Answer:

The slope is #3#.

Explanation:

The slope of a line in the form #y=mx+b# is #m#.

#3x-y=4#

#-y=-3x+4# subtract #3x# from both sides

#y=3x-4# multiply both sides by #-1#

#therefore# the slope is #3#

Answer:

#"slope "=3#

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=4" into this form"#

#"subtract 3x from both sides"#

#cancel(3x)cancel(-3x)-y=-3x+4#

#rArr-y=-3x+4#

#"multiply through by "-1#

#rArry=3x-4larrcolor(blue)"in slope-intercept form"#

#"with slope m "=3#
