(17, 42) and (-23, 32)
B
(9, -15) and (14, 19)
C
(5, 16) and (8, 18)
D
(20, 33) and (25, -29)
Answer & Analysis
Answer
D
Analysis
To find out which pair of points would yield a line with a negative slope, we use the slope formula: , where and are the coordinates of two points on the line.
Let's calculate the slope for each pair of points:
A. For the points and
Here , , , and .
The slope of the line passing through these points is positive.
B. For the points and
Here , , , and .
