Answer 1

Verified answer

Jawab :

1) a. y1 - y2 / x1 - x2 = 0 - 2 / 0 - 1 = -2/-1

b. y1 - y2 / x1 - x2 = 0 - (-3) / 0 - (-2)  = 3/2

Answer 2

Verified answer

Persamaan Garis

Misal :
gradien = m

Melalui (x1,y1) = (1,2)
PG :
y = m(x - x1) + y1
y = m(x - 1) + 2
y = mx + 2 - m ✔

Melalui (x1,y1) = (-2,-3)
y = m(x + 2) - 3
y = mx + 2m - 3 ✔
