Slope #= -1#
x-intercept #= 7#
y-intercept #= 7#

Explanation:

For a linear equation in standard form: #Ax+By = C#
the slope can be calculated as #m = -A/B#

Since for #x+y = 7#
#color(white)("XXXX")# #A=1##color(white)("XXXX")#and#color(white)("XXXX")##B=1#
the slope is #(-1)#

The x-intercept is the value of #x# when #y=0#
and
the y-intercept is the value of #y# when #x=0#
#rArr##color(white)("XXXX")#the x and y intercepts for the given equation are both #7#
