mohon bantu y kk no 11 sama jalanny y kk terimah ksh y kk

pakai rumus y-y1/y2-y1 = x-x1/x2-x1

y-1/6-1 = x-2/3-2

y-1/5 = x-2/1

5(x-2) = y-1
5x-10 = y-1
5x - y = -1 + 10
5x - y = 9 (A)

(2,1) dan (3,6)
x1= 2 x2= 3
y1= 1 y2= 6

y-y1/y2-y1 = x-x1/x2-x1
y-1/6-1 = x-2/3-2
y-1/5=x-2/1
kali silang
5(x - 2)= y - 1
5x - 10 = y - 1
5x - y - 10 = -1
5x - y = -1 + 10
5x - y = 9
