Use the given information to write the equation of each line

passing through (1,-4) and (-2,5)

y = -3x - 1

Step-by-step explanation:

The slope-intercept form of an equation of a line:

m - slope

b - y-intercept

The formula of a slope:

We have two points (1, -4) and (-2, 5).

Substitute:

Substitute the value of a slope and the coordinates of the point (1, -4) to the equation of a line:

           add 3 to both sides

Finally:

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.
