Answer:

#"slope "=-1/3" y-intercept "=2#

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 "x+3y=6" into this form"#

#"subtract x from both sides"#

#cancel(x)cancel(-x)+3y=6-x#

#rArr3y=-x+6#

#"divide all terms by 3"#

#rArry=-1/3x+2larrcolor(blue)"in slope-intercept form"#

#rArr"slope "=-1/3" and y-intercept "=2#
