• (4,7)

• (8,-14)

• (4,3)

• (2,3)

Segment AB has endpoints with coordinates A(3,6) and B(-2,-4). In simplest radical form, the length of segment AB is

The slope of the line that passes through the points (2,4) and (-1,9) is

Line l passes through the points (-5,3) and (3,7). If line m is perpendicular to line l, the slope of line m is equal to

Line l passes through the points (6,-14) and (2,-4). If line m is parallel to line l, the slope of line m is equal to
