The vertices of δrst are r(–7, 0), s(–3, 6), and t(9, 2). m is the midpoint of rt, and n is the midpoint of st. show that mn∥rs and mn=12rs.

i have to find the locations of m and n, the slopes of mn and rs, and the lengths of mn and rs.

Which approach to the theory-and-research cycle does the following sequence reflect: (1) specific observations suggest generalizations, (2) generalizations produce a tentative theory, (3) the theory is tested through the formation of hypotheses, and (4) hypotheses may provide suggestions for additional observations?
