			\[m=\frac{y_\NomB-y_\NomA}{x_\NomB-x_\NomA}=
			\frac{\AffCoeffFloat[]{\yB}-\AffCoeffFloatPa[]{\yA}}{\AffCoeffFloat[]{\xB}-\AffCoeffFloatPa[]{\xA}}=

			\ConversionFraction{\CoeffDirBrut}\]%
			%
			L'équation réduite de la droite est donc de la forme $(\NomA\NomB)$ : $y=\AffCoeffFAm[#1]{\CoeffDirBrut}+p$.\par
			%
			Il faut enfin déterminer l'ordonnée à l'origine $p$.\par
			%
			On sait que la droite passe par le point $\NomA$, donc les coordonnées $\NomA\left(\AffCoeffFloat[]{\xA};\AffCoeffFloat[]{\yA}\right)$ vérifient l'équation. On a alors :
			%
			\[y_\NomA=\ConversionFraction{\CoeffDirBrut} \times x_\NomA+p
			\implies 
			\AffCoeffFloat[#1]{\yA} = \ConversionFraction{\CoeffDirBrut} \times \AffCoeffFloatPa[#1]{\xA} + p \implies p = \AffCoeffFloat[#1]{\yA} - \left(\ConversionFraction{\CoeffDirBrut} \times \AffCoeffFloatPa{\xA}\right) \implies p = \OrdoOrigConv\]
			%
			Donc l'équation réduite de $(\NomA\NomB)$ est $y=\AffCoeffFAm[#1]{\CoeffDirBrut} \AffCoeffFAp[#1]{\OrdoOrigBrut}$.
