Kua tāruatia ki te papatopenga
y=-4x+12
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te x-3.
-4x+12=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-4x=y-12
Tangohia te 12 mai i ngā taha e rua.
\frac{-4x}{-4}=\frac{y-12}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{y-12}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
x=-\frac{y}{4}+3
Whakawehe y-12 ki te -4.
y=-4x+12
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te x-3.
