Graph the linear equation. find three points that solve the equation x-y=1

How about the following ordered pairs:
(4,3)  (3,2) and (2,1).. you might consider writing the equation in the following form:  y = x - 1 to generate additional ordered pairs..

To graph:  plot the point (0,-1)... from this point to get additional points, just go up 1 and to the right one from each additional point.  You could also go down one and to the left one..   Happy Graphing! 

Istg idk..if there all the same length there all the same number but use google

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
