2. what is the slope of the line?
a.) 0
b.) 1
c.) undefined
d.) infinity

The slope of a vertical line is not defined or it is said to be infinite since by definition the slope is the tangent of the angle that forms the line with the horizontal direction. Since in this case the angle is 90 degrees, the tangent of 90 degrees is infinite.
The answer is D.) Infinity

The answer is lol i dont know

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.
