1)memiliki kemiringan 4 dan melalui titik (-2,1) 2.melalui (1,4) dan (2,-1) 3.melalui (-1,0) dan (3,-8)

1 ) yg no 1 , apa yg di tanya -_-
2 )m =  Δy/ Δx = y2-y1 / x2 - x1
m = -1 - 4 / 2-1
m = -5 / 1
m = -5
3 ) m = Δy/ Δx = y2-y1 / x2 - x1
m = -8 - 0 / 3 - (-1)
m = -8 / 4
m = -2

y = 4x - 7 --> jawabanny no. 1
