The slope is #-1/2# and the y-intercept is #-4#.

Problem: Find the slope and y-intercept for #x+2y=-8#.

Convert the equation into the slope-intercept form.

The slope-intercept equation is #y=mx+b#, where #m# is the slope, and #b# is the y-intercept.

#x+2y=-8#

Subtract #x# from both sides of the equation.

#2y=-x-8#

Divide both sides of the equation by #2#.

#y=-1/2x-4#

#m=-1/2#

#b=-4#
