Solve the system of linear equations by graphing y=-x-2 y=x find were the lines intercept

2 lines intercept at (0,0) and (-1,-1) Hope this help :3

Step-by-step explanation:

For this case we have the following system of equations:

If we substitute the second equation in the first we have:

So:

Thus, the lines intersect at:

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.

The answer is the first one
