#### Explanation:

You can easily find the slope of any line by rewriting its equation in sloper-intercept form, which for a general line looks line this

#color(blue)(y = mx + b)" "# , with

Your line equation looks like this

#x + y = 7#

To get it to general slope-intercept form, move

#y = -x + 7#

Now simply compare the two equations. In your case, you have

#m = color(green)(-1)#
