FP3.5.3 - Equation of a plane

The equation of a plane in the Students may be required to use equivalent cartesian forms forms also. r.n = p, r = a + sb + tc.

Use fp3.5.3 - equation of a plane to connect the rule to the data and decision in the question.

This matters because fp3.5.3 - equation of a plane determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply fp3.5.3 - equation of a plane to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: use the formula and units given in the question, show the substitution and interpret the result; the calculation alone is not the conclusion.
