From the listed coordinates, the pair that has a slope of 2/5 are (-1, 1) and (-6, -1), (1, 0) and (6, 2), (3, 0) and (8, 2)
Parallel and perpendicular lines
For lines to be parallel, they must have the same slope, while for two lines to be perpendicular, the product of their slopes must be -1
Given the coordinate points (3, 4) and (-2, 2)
The slope is calculated as:
[tex]m =\frac{2-4}{-2-3}\\ m=\frac{-2}{-5}\\ m = 2/5[/tex]
We need to select the coordinate points that have the same slope. From the listed coordinates, the pair that has a slope of 2/5 are (-1, 1) and (-6, -1), (1, 0) and (6, 2), (3, 0) and (8, 2)
