probability of drawing ace: 4/52 = 1/13
probability of drawing 9: 4/52 = 1/13
probability of drawing ace or 9: 1/13 + 1/13 = 2/13 or ~15.4%
Distance = rate x time
Distance = 221 miles
Rate = 68 mph
221 miles = 68 mph x time
221 miles/68 mph = time
3.25 hours = time
Positive 18, going off the assumption that the tick 2 spaces away from -1 is positive 9.

now, a line perpendicular to that one, will have a "negative reciprocal" slope, thus
