Whakaoti i te y+1=-1/2(x+7)

$$y + 1 = - \frac { 1 } { 2 } ( x + 7 )$$

Whakaoti mō x

$$x=-2y-9$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -\frac{1}{2} ki te x+7.

$$y+1=-\frac{1}{2}x-\frac{7}{2}$$

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

$$-\frac{1}{2}x-\frac{7}{2}=y+1$$

Me tāpiri te \frac{7}{2} ki ngā taha e rua.

$$-\frac{1}{2}x=y+1+\frac{7}{2}$$

Tāpirihia te 1 ki te \frac{7}{2}, ka \frac{9}{2}.

$$-\frac{1}{2}x=y+\frac{9}{2}$$

Me whakarea ngā taha e rua ki te -2.

$$\frac{-\frac{1}{2}x}{-\frac{1}{2}}=\frac{y+\frac{9}{2}}{-\frac{1}{2}}$$

Mā te whakawehe ki te -\frac{1}{2} ka wetekia te whakareanga ki te -\frac{1}{2}.

$$x=\frac{y+\frac{9}{2}}{-\frac{1}{2}}$$

Whakawehe y+\frac{9}{2} ki te -\frac{1}{2} mā te whakarea y+\frac{9}{2} ki te tau huripoki o -\frac{1}{2}.

$$x=-2y-9$$

Whakaoti mō y

$$y=\frac{-x-9}{2}$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te -\frac{1}{2} ki te x+7.

$$y+1=-\frac{1}{2}x-\frac{7}{2}$$

Tangohia te 1 mai i ngā taha e rua.

$$y=-\frac{1}{2}x-\frac{7}{2}-1$$

Tangohia te 1 i te -\frac{7}{2}, ka -\frac{9}{2}.

$$y=-\frac{1}{2}x-\frac{9}{2}$$
