Tent. Persamaan garis (4,-1 dan 2,-5)

m=-5+1/2-4
=-4/-2=2
y-y1=m(x-x1)
y+1=2(x-4)
y+1=2x-8
y-2x=-8-1
y-2x=-9
maaf klo ada kesalahan

Jawab :

y2 - y1/ x2 - x1 = (-5) - (-1)/ 2 - 4 = -4/-2 = 2

persamaannya :

y - y1 = m(x - x1)
y - (-1) = 2(x - 4)
y + 1 = 2(x - 4)
y + 1 = 2x - 8
y = 2x - 8 - 1
y = 2x - 9
