tentukan peramaan garis dari a.(3,4) dan (-2,1) b.11y+2×-5=0 c.(3,0) dan (6,0) pakai cara

A. y - y1/y2 - y1 = x - x1/x2 - x1

y-4/1-4 = x-3/-2-3
y-4/-3 = x-3/-5

-3(x-3) = -5(y-4)
-3x+9 = -5y+20
-3x = -5y+20-9
-3x = -5y+11
atau -3x+5y-11 = 0

C. y-y1/y2-y1 = x-x1/x2-x1

y-0/0-0 = x-3/6-3
y-0/0 = x-3/3

0(x-3) = 3(y-0)
0x-0 = 3y-0
0x = 3y-0+0
0x = 3y-0
atau x-3y = 0
nb : 0 bisa dihilangkan di akhir angka.

semoga membantu:)
