y2-y1 x2-x1
y1 = 7
y2 = -3
x1 = -2

subsitusikan saja
y-7 = x-(-2) = y-7 = x+2

kali 10
-y+7 = 2x + 4
2x + y -7 + 4 = 0
2x + y - 3= 0 ⇔⇔ y = -2x + 3
x1= -2
x2 = 3
y1 = 7
y2 = -3
ditanya: persamaan garis lurus?
penyelesaian:
y-y1/y2-y1=x-x1/x2-x1
y-7/-3-7=x+2/3+2
y-7/-10=x+2/5
5(y-7)=-10(x+2)
5y-35=-10x-20
5y=-10x-20+35
5y=-10x+15
