Maka : x1 = -4 y1 = 7
x2 = 10 y2 = -1
y - y1 = x - x1
y2 - y1 x2 - x1
y - 7 = x - (-4)
-1 - 7 10 - (-4)
y-7 = x+4
-1 - 7 10 + 4
y-7 = x+4
-8 14
14(y-7) = -8(x+4)
14y - 98 = -8x - 32
14y + 8x = 98 - 32
14y + 8x = 66 | kedua ruas di bagi 2
7y + 4x = 33
7y + 4x - 33 = 0
Jawaban C. 7y + 4x - 33 = 0
Sory klo salah
y - 7 / -1 - 7 = x + 4/10 + 4
y-7 / -8 = x + 4 / 14
14(y-7) = -8(x + 4)
14y - 98 = -8x - 31
14y = -8x -31 + 98
14y = -8x +67
7y = -4x + 33
b.7y + 4x - 33 = 0
