Find the slope of the line.

Question

(-3,1) (4,-1)

What is the slope of the​ line? Select the correct choice below​ and, if​ necessary, fill in the answer box to complete your choice.

A. The slope of the line is _____

B. The slope of the line is undefined.

Answer 1

The slope of a line can be found using the formula:

slope = (change in y-coordinates)/(change in x-coordinates)

Given the two points (-3,1) and (4,-1), the change in y-coordinates is -1 - 1 = -2, and the change in x-coordinates is 4 - (-3) = 7.

Therefore, the slope of the line is -2/7.

So, the correct choice is:

A. The slope of the line is -2/7.
