For k={(x, y) | x-y=5}, and the domain of x=0,2,4 select the graph that represents the set of data.

x-y = 5

replace x with the given values to solve for y:

0-y = 5, y = -5

2 - y = 5, y = -3

4-y = 5, y = -1

Now you have points (0,-5), (2,-3) and (4,-1)

The attached picture is the correct graph:

c. side angle side. u shares the same sides
