gradien 2/3 adalah….
A 2x-3y + 2 = 0
B. 3x – 3y + 2 = 0
C. 2x + 3y + 3 = 0
D. x-3y + 12 = 0
32. Persamaan garis melalui titik (5,4) dengan
Jawaban:
titik (x¹, y¹) => (5,4)
gradien => m = 2/3
maka,
y – y¹ = m (x – x¹)
y – 4 = 2/3 (x – 5)
3(y – 4) = 2(x – 5)
3y – 12 = 2x – 10
2x – 10 – 3y + 12 = 0
2x – 3y – 10 + 12 = 0
2x – 3y + 2 = 0 (A)
