Answer:

Slope = -1
y-intercept = -5

Explanation:

#x+y=-5#

If you rearrange it to standard form #y=mx+b# (m being the slope and b being the y-intercept)

#y=-x-5#

#m=-1#
#b=-5#

Answer:

See solution process below:

Explanation:

First, the equation needs to be rewritten into Slope-Intercept Form, which is #y = mx + b#, where "m" is the slope, and "b" is the y-intercept, by solving for y.

#x + y = -5#
#y = -5 - x#
#y = -x + 5#

To find the slope and y-intercept of any equation in Slope-Intercept Form, your "m" value will represent slope, and your "b" value will represent the y-intercept.

In this equation: #y = -x + 5#, there is no written number for the m value, but x is still technically being multiplied by 1, so "m", or slope, can be represented with "-1".

Since there is a value for "b", or y-intercept, it can be represented with 5.
