Question

Quizplus · Accepted Answer

The slope of a line passing through two points (x1, y1) and (x2, y2) is given by the formula:

slope = (y2 - y1) / (x2 - x1)

Using the given points (15, 10) and (7, 30):

slope = (30 - 10) / (7 - 15) = -20 / (-8) = 5 / 2

However, the question asks for the slope of the line in the opposite direction (i.e. from right to left), which is just the negative of the slope calculated above:

slope = -5 / 2

Therefore, the best choice is A) -5/2.
