4-4 Parallel and Perpendicular Lines
So, the correct choice is B.
A line through which two points would be parallel to a line with a slope of
?
(0, 5) and ( 4, 2)
(0, 2) and ( 4, 1)
(0, 0) and (0, 2)
(0, 2) and ( 4, 2)
Find the slope of the points for choice F.
This is the same slope as that of the given line, so the correct choice is F.
