Find the slope of the line that passes through the pair of points.
(5.3, –2.5), (7.3, –12.5)
A. 0.2
B. -0.2
C. 5
D. -5
The slope of a line passing through the points (x1, y1) and (x2, y2) can be calculated using the formula:
Slope = (y2 - y1) / (x2 - x1)
In this case, the points are (5.3, -2.5) and (7.3, -12.5):
Slope = (-12.5 - (-2.5)) / (7.3 - 5.3)
Slope = (-12.5 + 2.5) / 2
Slope = -10 / 2
Slope = -5
Therefore, the slope of the line passing through the points (5.3, -2.5) and (7.3, -12.5) is -5.
The correct answer is D. -5.
