Question

Tentukan persamaan garis yang melalui pasangan pasangan titik R(-4,7) dan S(-3,-1) tolong jawab

Answer 1

Verified answer

R (-4, 7) dan S (-3, -1)

x1 = -4
y1 = 7
x2 = -3
y2 = -1

(y - y1) / (y2 - y1) = (x - x1) / (x2 - x1)
(y - 7) / ((-1) -7) = (x - (-4)) / ((-3) -(-4))
(y - 7) / (-8) = (x + 4) / (1)
y - 7 = (-8)(x + 4)
y - 7 = -8x - 32
y = -8x - 32 + 7
y = -8x - 25

atau
8x - y + 25 = 0
