Original question and givens

Use only the explicitly supplied rule, symbols and finite pair table. Graph appearance supplies no values, and agreement on the listed inputs proves no equivalence on unlisted domains. a=2, b=4, pairs=[[0, 4], [1, 6], [2, 8]]. Normalize tuple collections by removing identical tuples and sorting their JSON strings with the source’s en-locale comparison. This is canonical record order, not numerical coordinate order; number any output rows from 0 only after that normalization. Give (a,b,every [x,listed y,a*x+b,match?] row,all rows match?).

  • G001 — Use only the explicitly supplied rule, symbols and finite pair table.

Definition and scope

Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.

Step-by-step derivation

S001 · implies

Before

declared symbolic rule or complete finite table

After

keep the stated domain and representation distinct

Conditions: none

Use only the declared rule or table;agreement on a finite table alone does not establish function equality on an unlisted domain.

Step identifiers and dependencies

Rule: representation_scope · Uses: G001

S002 · calculation

Before

audit x=0 ax := mul(2, 0)

After

audit x=0 ax = 0

Conditions: none

Evaluate a·x first;do not replace the rule by a(x+b).

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S001

S003 · calculation

Before

audit x=0 ax+b := sum(0, 4)

After

audit x=0 ax+b = 4

Conditions: none

Then add the intercept b,fully substituting this input.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S002

S004 · implies

Before

listed y=4; rule ax+b=4

After

agreement=Yes

Conditions: none

Compare each listed output with the exact rule value;visual proximity is not equality.

Step identifiers and dependencies

Rule: representation_row_agreement · Uses: G001, S003

S005 · calculation

Before

audit x=1 ax := mul(2, 1)

After

audit x=1 ax = 2

Conditions: none

Evaluate a·x first;do not replace the rule by a(x+b).

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S004

S006 · calculation

Before

audit x=1 ax+b := sum(2, 4)

After

audit x=1 ax+b = 6

Conditions: none

Then add the intercept b,fully substituting this input.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S005

S007 · implies

Before

listed y=6; rule ax+b=6

After

agreement=Yes

Conditions: none

Compare each listed output with the exact rule value;visual proximity is not equality.

Step identifiers and dependencies

Rule: representation_row_agreement · Uses: G001, S006

S008 · calculation

Before

audit x=2 ax := mul(2, 2)

After

audit x=2 ax = 4

Conditions: none

Evaluate a·x first;do not replace the rule by a(x+b).

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S007

S009 · calculation

Before

audit x=2 ax+b := sum(4, 4)

After

audit x=2 ax+b = 8

Conditions: none

Then add the intercept b,fully substituting this input.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S008

S010 · implies

Before

listed y=8; rule ax+b=8

After

agreement=Yes

Conditions: none

Compare each listed output with the exact rule value;visual proximity is not equality.

Step identifiers and dependencies

Rule: representation_row_agreement · Uses: G001, S009

S011 · implies

Before

[Yes, Yes, Yes]

After

Yes

Conditions: none

All listed rows must agree;one counterexample refutes consistency of this table with the rule.

Step identifiers and dependencies

Rule: all_representation_rows · Uses: G001, S010

Reverse checks

  • S011 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
  • S010 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
  • S009 · premise_and_result_audit — Recompute audit x=2 ax+b with exact rational arithmetic, not rounded decimals.
  • S008 · premise_and_result_audit — Recompute audit x=2 ax with exact rational arithmetic, not rounded decimals.
  • S007 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
  • S006 · premise_and_result_audit — Recompute audit x=1 ax+b with exact rational arithmetic, not rounded decimals.
  • S005 · premise_and_result_audit — Recompute audit x=1 ax with exact rational arithmetic, not rounded decimals.
  • S004 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
  • S003 · premise_and_result_audit — Recompute audit x=0 ax+b with exact rational arithmetic, not rounded decimals.
  • S002 · premise_and_result_audit — Recompute audit x=0 ax with exact rational arithmetic, not rounded decimals.
  • S001 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.

Result

(2, 4, [[0, 4, 4, Yes], [1, 6, 6, Yes], [2, 8, 8, Yes]], Yes)

The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
