Find the slope of the line that passes through the pair of points.
(–5.5, 6.1), (–2.5, 3.1)
A. -1
B. -3/8
C. 1
D. 3/8
The slope formula is given by:
m = (y2 - y1) / (x2 - x1)
Using the points (-5.5, 6.1) and (-2.5, 3.1), we get:
m = (3.1 - 6.1) / (-2.5 - (-5.5))
m = -3 / 3
m = -1
Therefore, the slope of the line passing through these points is -1.
The correct answer is A. -1.
