tolong pakai cara nya

a) x + 3y = o
= 3y = -x + o : 3 ~~~~~~~~ garis lurus
= y = -x/3

b) = 2y = -x² + 5~~~~~~ bukan garis lurus

c) 3y = -3x + 9 : 3
y = -x + 3 ~~~~~~~~~~~ garis lurus

d) y/3 = -3x + 12
= y/3 × 3 = -3x.3 + 12.3 ~~~ garis lurus
y = -9x + 36

e) bukan garis lurus

d) bukan garus


Semoga benar :v
