Soal:
Persamaan garis yang melalui titik (-2,4) dan (6,3) adalah....
Penjelasan dengan langkah-langkah:
Gradien (m)
= (y2-y1)/(x2-x1)
= (3-4) / (6-(-2))
= (-1) / (8)
= - 1/8
Persamaan Garis
= y-y1 = m(x-x1)
= y-4 = -1/8 (x-(-2)
= 8(y-4) = -1 (x+2)
= 8y-32 = -x + -2
= x+8y = 32-2
= x + 8y = 30
= x + 8y - 30 = 0
Jadi Jawabannya B. x + 8y - 30 = 0
Semoga membantu '-')/
