A. Tentukan persamaan garis bergeradien 8 melalui titik (1,-3) B. Tentukan persamaan garis melalui titik (2,4) dan (3,2) C. Tentukan persamaan garis melalui tit

a.) m=8 (1,-3)
y-b = m(x-a)
y-(-3)= 8(x-1)
y+3 = 8x-8
-8x+y= -8+3
-8x+y= -5

b.) (2,4) dan (3,2)
y-y1 x-x1
____ = ____
y2-y1 x2-x1

y-4 x-2
____ = ____
2-4 3-2

y-4 x-2
____ = ____
-2 1

1(y-4) = -2(x-2)
y-4 = -2x+4
2x+y = 4+4
2x+y = 8

c.) 3x+5y-6=0
5y=-3x+6
y =-3/5x+6/5
m1=m2=-3/5
(2,-4)
y-b = m(x-a)
y-(-4) = -3/5(x-2)
5(y+4)= -3(x-2)
5y+20= -3x+6
3x+5y=6-20
3x+5y=-14

d.)y=2x+3
m1=2
m2=-1/2
(-2,3)
y-b = m(x-a)
y-3 = -1/2(x-(-2))
y-3 = -1/2(x+2)
2(y-3)= -1(x+2)
2y-6 = -x-2
x+2y = -2+6
x+2y = 4
