Question

Tentukan Persantaan garis yang melalui titik (-5,2) dan (4,1)​

Answer 1

Jawaban:

m=Y2-Y1/X2-X1

=(1-2)/(4-(-5))

=-1/(4+5)

=-1/9

Y-y1=m(X-x1)

Y-2=-1/9(X-(-5)

Y-2=-1/9(X+5)

Y-2=-1/9X-5/9

Y=-1/9X-5/9+2

Y=-1/9X-5/9+18/9

Y=-1/9X+13/9

-----------------x9

9Y=-X+13

X+9Y=13

X+9Y-13=0

semoga membantu
