Write the equation of a line that is perpendicular to y=-x-6 and that passes through the point (-9,-4)

Given line : y = -x - 6

Comparing it with y = mx + c

slope of line, m = -1

So the slope of the line perpendicular to it will be = -1/m = -1/(-1) = 1

So the perpendicular line will be of the form: y = x + k

where k is a constant.

It passes through (-9,-4)

Thus

-4 = (-9) + k

=> k = (-4) + 9

=> k = 5

Thus, equation of perpendicular line is y = x + 5

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.
