Dik: Persamaan garis y= mx+c. Tentukan nilai m dan c jika garis tersebut melalui titik (-4,2) dan (3,-3)

titik (-4,2) dan (3,-3)
(y-y1)/(y2-y1) = (x-x1)/(x2-x1)
<=> (y-2)/(-3-2) = (x+4)/(3+4)
<=> (y-2)/(-5) = (x+4)/(7)
<=> 7(y-2) = -5(x+4)
<=> 7y-14 = -5x-20
<=> 7y = -5x-20+14
<=> 7y = -5x-6
sehingga nilai
m = -5
c = -6
