Question

Tentukn prsamaam garis yg melalui titik brkt
a.(1,4) dan (2,7)
b.(2,3) dan (-6,1)

Answer 1

Y2-y1/x2-x1=7-4/2-1=3/1=1

y-y1=m(x-x1)
y-4=1(x-1)
y-4=x-1
y=x-1+4
y=x+3

Answer 2

A. (1,4) dan (2,7)
rumus
y-y1/y2-y1 = x-x1/x2-x1
dik : x1=1 x2=2 y1=4 y2=7
y-4/7-4 = x-1/2-1
y -4/3 = x-1
y-4 =3(x-1)
y-4 = 3x-3
0 =3x-y+4-3
3x-y+1
3x-y=-1....jawaban
b. (2,3) dan (-6,1)
rumus
y-3/1-3 = x-2/-6-2
y-3/-2 = x-2/-8
-8(y-3) = -2(x-2)
-8y+24 = -2x+4
2x-8y+24-4= 0
2x-8y+20 /2
x-4y+10
x-4x = -10...jawaban
