Whakaoti i te y=-2/5x+6

$$y = \frac { - 2 } { 5 } x + 6$$

Whakaoti mō x

$$x=-\frac{5y}{2}+15$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Ka taea te hautanga \frac{-2}{5} te tuhi anō ko -\frac{2}{5} mā te tango i te tohu tōraro.

$$y=-\frac{2}{5}x+6$$

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

$$-\frac{2}{5}x+6=y$$

Tangohia te 6 mai i ngā taha e rua.

$$-\frac{2}{5}x=y-6$$

Whakawehea ngā taha e rua o te whārite ki te -\frac{2}{5}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{-\frac{2}{5}x}{-\frac{2}{5}}=\frac{y-6}{-\frac{2}{5}}$$

Mā te whakawehe ki te -\frac{2}{5} ka wetekia te whakareanga ki te -\frac{2}{5}.

$$x=\frac{y-6}{-\frac{2}{5}}$$

Whakawehe y-6 ki te -\frac{2}{5} mā te whakarea y-6 ki te tau huripoki o -\frac{2}{5}.

$$x=-\frac{5y}{2}+15$$

Whakaoti mō y

$$y=-\frac{2x}{5}+6$$
