Plot the 1st point (-1,1)

Plot the 2nd point (-2,2)

Plot the 3rd point (-3,3)

Plot the 4th point (-4,4)

So the graph of the relation {(-1,1),(-2,2),(-3,3),(-4,4)} is

Remember, the domain is simply the set of values that you can plug in (ie the x values). So the domain is {-1,-2,-3,-4} (these are the x-coordinates of the points).

Also, the range is the set of values that come out (ie the y values). So the range is {1,2,3,4} (these are the y-coordinates of the points).
