Jawab17. persamaan garis
A(x1,y1) = -1,4)
B(x2,y2) = (6,1)
gradien garis m = (y2 - y1) / (x2 - x1)
m = (1 - 4). /(6 +1)
m = -3/7
18., garis g melalui (-1,0) dan (0, -2)
y - 0 = (-2)(x + 1)/(1)
y = -2( x+ 1)
y = -2x - 2
2x + y = -2
garis h sejajar g melalui (0,6)
2x + y = 0(2) + 1(6)
2x + y = 6
y = -2x + 6
