#"slope "=-1/2," 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 "-3x=6y+18" into this form"#

#"subtract 18 from both sides"#

#-3x-18=6y#

#"divide all terms by 6"#

#-1/2x-3=y#

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

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