In the rational setting, the fixed factor is k=-7. Does the explicit point (x,y)=(2,-13) satisfy y=kx? Check only this point.
G001 — In the rational setting, the fixed factor is k=-7. Does the explicit point (x,y)=(2,-13) satisfy y=kx? Check only this point.
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.
Check THIS bank’s keys/operation/domain:legacy table underscores,MOD50 local hyphens;permissive BASE data acquires no unknown-field restriction.Keep Number.isInteger and SAFE source guards distinct,while preserving ORIGINAL JSON number representations.
Proportion ORIGINAL fixed factor times point x := mul(-7, 2)
After
Proportion ORIGINAL fixed factor times point x = -14
Conditions: none
Calculate exactly from ORIGINAL ordered operands.Legacy derived integers are not recapped at the RAW SAFE bound;MOD50 rationals separately retain the NAIVE pre-reduction source envelope.
Check ONLY THIS point against y=kx.Zero k or x is allowed.One passing point does not establish proportionality for other inputs,nor does x=0 determine a unique factor.

Result
No
The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
