Answer:

A straight line through #(0, -7)# and #(7, 0)#

Explanation:

#x-y=7# can be rewritten as #y=x-7#

This is the equation of a straight line of slope = 1 and y-intecept of #-7#

Since the graph is a straight line only need two points to plot it.

For simplicity, I will choose #(0, -7)# and #(7, 0)#

The graph of the line is shown below.
