Generate and plot ordered pairs from rules, tables, and contexts.
Match coordinates and plots to a relationship
Problem
Which candidate ordered pairs satisfy \(y~=~x~+~2\)?
A. \((1,~3)\) B. \((3,~1)\) C. \((4,~6)\) D. \((0,~2)\) E. \((5,~8)\) F. \((2,~5)\)
Big Picture
What this problem is really about
Each labeled pair must pass the same two-part check: its first number plays x, and the rule’s computed value must equal its second number. Test every label by substitution, record matches as you go, and do not let familiar numbers or reversed coordinates substitute for the equation. A complete set is trustworthy only after all six pairs have been checked.
