Whakaoti i te y-4=-2/3(x+2)

$$y - 4 = - \frac { 2 } { 3 } ( x + 2 )$$

Whakaoti mō x

$$x=-\frac{3y}{2}+4$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -\frac{2}{3} ki te x+2.

$$y-4=-\frac{2}{3}x-\frac{4}{3}$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$-\frac{2}{3}x-\frac{4}{3}=y-4$$

Me tāpiri te \frac{4}{3} ki ngā taha e rua.

$$-\frac{2}{3}x=y-4+\frac{4}{3}$$

Tāpirihia te -4 ki te \frac{4}{3}, ka -\frac{8}{3}.

$$-\frac{2}{3}x=y-\frac{8}{3}$$

Whakawehea ngā taha e rua o te whārite ki te -\frac{2}{3}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{-\frac{2}{3}x}{-\frac{2}{3}}=\frac{y-\frac{8}{3}}{-\frac{2}{3}}$$

Mā te whakawehe ki te -\frac{2}{3} ka wetekia te whakareanga ki te -\frac{2}{3}.

$$x=\frac{y-\frac{8}{3}}{-\frac{2}{3}}$$

Whakawehe y-\frac{8}{3} ki te -\frac{2}{3} mā te whakarea y-\frac{8}{3} ki te tau huripoki o -\frac{2}{3}.

$$x=-\frac{3y}{2}+4$$

Whakaoti mō y

$$y=\frac{8-2x}{3}$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te -\frac{2}{3} ki te x+2.

$$y-4=-\frac{2}{3}x-\frac{4}{3}$$

Me tāpiri te 4 ki ngā taha e rua.

$$y=-\frac{2}{3}x-\frac{4}{3}+4$$

Tāpirihia te -\frac{4}{3} ki te 4, ka \frac{8}{3}.

$$y=-\frac{2}{3}x+\frac{8}{3}$$
