Question

Persamaan garis melalui titik (5,2) dan (3,-4) adalah

Answer 1

Y-y1 / y2-y1 = x-x1 / x2-x1
y-2/-4-2 = x-5/3-5
y-2/2=x-5/-2
2y-4 = -2x + 10
2y + 2x -14 = 0

Answer 2

Y - y1 / y2 - y1 = x - x1 / x2 - x1
y - (-4) / 2 - (-4) = x - 3 / 5 - 3
y + 4 / 6 = x - 3 / 2
y + 4 / 3 = x-3
y + 4 = 3 (x-3)
y + 4 = 3x - 9
0 = 3x - y - 13
