Is it possible to place dominoes (in the manner described) in such a way as to cover all s2 - 2 squares of the modified board? for this problem, we'll establish an invariant that can then be used to us prove that the answer to this question is no. (5 pts) let diff = (# of uncovered white squares) - (# of uncovered black squares) in the initial modified board (i. e., before any dominoes have been placed).

If the slope of one line equals the slope of another line then ? a) the two lines are intersecting lines b) the two lines are perpendicular lines c) the two lines are parallel lines d) the two lines always have very steep slopes
