Question

Persamaan garis yang melalui titik (2,-3) dan sejajar garis 5x+4y=9 adalah....

Answer 1

Tips cepat :
5x + 4y = 5xi + 4xi
5x + 4y = 5.2 + 4(-3)
5x + 4y = 10-12
5x + 4y = -2
5x + 4y + 2 = 0

Answer 2

M = -5/4
persamaan garis : y-y1 = m(x-x1)
y - (-3) = -5/4 (x-2)
y+3 = -5/4x + 5/2
4(y+3) = -5x + 10
4y +12 = -5x + 10
5x + 4y +2 = 0
