x-intercept: #4#
y-intercept: #-4#

Explanation:

The x-intercept is the value of #x# where the equation crosses the X-axis; note that the X-axis is the collection of points for which #y=0#, so another way of saying this is: the x-intercept is the value of #x# when #y=0#
#(x-y=4)# with #y=0 rarr (x-0=4) rarr (x=4)#

Similarly, the y-intercept is the value of #y# when #x=0#
#(x-y=4)# with #x=0 rarr (0-y=4) rarr (y=-4)#
