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 x-values are the same, it's vertical

if both y-values are the same, it's horizontal.
