What is the slope of y = 3.5x and what does this mean?

The answer would be slope = 3.5. I got this because in most situations the number next to the X variable in an equation is the slope. Hope this helps.

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.
