Find the slope of the line that passes through the given pair of points. (if an answer is undefined, enter undefined.) (−5, −5) and (9, −9)

To find the slope of the line between two points, we use the equation

Where m is the slope of the line. Now, we substitute our given values into the equation, and solve for m:


So, the slope of the line is - 2/7

There is 240 red cars and there is 400 blue cars because 240/3=80 and 80*5=400
