The slope is #1# and the y-intercept is #7#.

Explanation:

#x-y=-7# is in the standard form for a linear equation. The slope intercept form is #y=mx+b#, where #m# is the slope and #b# is the y-intercept. In order to convert from standard to slope intercept form, solve the standard form for #y#.

#x-y=-7#

Subtract #x# from both sides.

#-y=-7-x#

Multiply both sides times #-1#.

#y=7+x#

Rearrange.

#y=x+7#

The slope is #1# and the y-intercept is #7#.
