Question

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

Answer 1

Verified answer

Y - y1/y2-y1 = x-x1/x2-x1
y - (-4) / 3 - (-4) = x - (-2) / -4-(-2)
y + 4 / 7 = x + 2 /-2
-2(y + 4) = 7(x + 2)
-2y + -8 = 7x + 14
0 = 7x + 2y + 14 + 8
0 = 7x + 2y + 22

Answer 2

Verified answer

Y-y1/y2-y1 = x-x1/x2-x1
y-(-4)/3-(-4) = x-(-2)/-4-(-2)
y+4/3+4 = x+2/-4+2 (kali silang)
-2y-8 = 7x+14
7x+2y+14+8 = 0
7x+2y+22 = 0
