Using the information given, select the statement that can deduce the line segments to be parallel. if there are none, then select none.

when m< 2 = m< 6

The second choice is correct.  Given that angle 2 and angle 6 are congruent, the largest in each of the corresponding triangles are vertical angles meaning that two known angles are known in each triangle (and they are equal) which means that the last "unknown" (angles 3 and 7) are congruent.  The lines DC and AB correspond with these defined, congruent triangles meaning they are parallel.

Divide 40%5 and your answer is 8

the image of (6, 9) under a dilation is (4, 6). the scale factor is
