Explanation:

#y=-x+8# is the slope-intercept form, which is #y=mx+b#.
The number in front of # x # is the slope and #b# is the y-intercept.

The y-intercept for this equation is #8#, or #(0,8)#
You put a point at #(0,8)#. That's the starting point for your slope.

The number in front of #x# is #-1#
That means the line rises #-1# (goes down by one unit) and runs #1# (moves to the right by one unit)
