#"slope "=-1," y-intercept "=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 "x+y=3" into this form"#

#"subtract x from both sides"#

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

#"with slope "=-1" and y-intercept "=3#
