Titik (-4, 5) melalui persamaan garis…​

Jawaban:

Titik (-4, 5) melalui persamaan garis 5y = 4x + 41

PENJELASAN :

m = - frac{( - 4)}{5} = frac{4}{5} \ \ y - y1 = m(x - x1) \ y - 5 = frac{4}{5} (x - ( - 4)) \ y - 5 = frac{4}{5} x + frac{16}{5} | times 5 \ 5y - 25 = 4x + 16 \ 5y = 4x + 16 + 25 \ 5y = 4x + 41
