• P (4,0)

• P (6,0)

• P (3,0)

• P (8,0)

Answer explanation

If the ratio is 1:2, that means the scale factor is  $\frac{1}{3}$  . The run from 0 to 12 is 12 and the rise from 0 to 0 is 0. A third of 12 is 4 and a third of zero is zero.  Add the new run, 4, to the orignial x-value zero to get new x-value four, and add the new rise zero to the original y-value zero to get new y-value zero.

True/False: a directed line segment has both distance and direction.

• True

• False

• True

• False

Answer explanation

Directed line segments have a specific direction. If it is called  $\overline{MN}$  , it MUST go from M to N. If it goes from N to M, it must be called  $\overline{NM}$
