Find the slope of the line.
(-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.
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.
