1. Determine which ordered pair is a solution of y = x*2–2.
(5, 21), (–5, 24), (–1, –1), (–2, 6)
2. Without graphing, tell whether the line containing (6, –3) and (0, –8) is horizontal, vertical, or neither.

just try each pair. Looks like (1,1)
2.
If both xvalues are the same, it's vertical
if both yvalues are the same, it's horizontal.
