Question

Tolong jawab pliss, soalnya di gambar pke caranya juga jawabnya dan tolong secepatnya ya!! tolong jawab no 2 dari B,C,D,E

Answer 1

A. (x1,y1) » (0,0)
(x2,y2) » (1,3)
(y-y1)/(y2-y1)=(x-x1)/(x2-x1)
(y-0)/(3-0)=(x-0)/(1-0)
y/3=x/1
y=3x

b. (x1,y1) » (6,0)
(x2,y2) » (0,3)
(y-y1)/(y2-y1)=(x-x1)/(x2-x1)
(y-0)/(3-0)=(x-6)/(0-6)
y/3=(x-6)/(-6)
-6y=3x-18
3x+6y-18=0

c. (x1,y1) » (-4,0)
(x2,y2) » (0,7)
(y-y1)/(y2-y1)=(x-x1)/(x2-x1)
(y-0)/(7-0)=(x+4)/(0+4)
y/7=(x+4)/4
4y=7x+28
7x-4y+28=0

d. (x1,y1) » (-3,0)
(x2,y2) » (0,-6)
(y-y1)/(y2-y1)=(x-x1)/(x2-x1)
(y-0)/(-6-0)=(x+3)/(0+3)
y/(-6)=(x+3)/3
3y=-6x-18
6x+3y+18=0

e. (x1,y1) » (2,0)
(x2,y2) » (0,-7)
(y-y1)/(y2-y1)=(x-x1)/(x2-x1)
(y-0)/(-7,0)=(x-2)/(0-2)
y/(-7)=(x-2)/(-2)
-2y=-7x+14
7x-2y-14=0
