Kata kunci : persamaan garis
Mapel : Matematika

5) => y = 1/2x + c
=> (0,5) , x = 0 dan y = 5
=> nilai c = ...?
=> y = 1/2x + c
=> 5 = 1/2 (0) + c
=> 5 = c , jawaban benar opsi b. 5

6) => A (-1,2) dan (5,-2)
=> gradien (m) ...?
=> m = (y2 - y1) / (x2 -x1)
=> m = (-2 - 2) / (5 - (-1))
=> m = -4/6 = -2/3. jawaban benar opsi b . -2/3

7) => P(1,1) dan Q (1,4)
=> m ...?
=> m = (y2 - y1) / (x2 -x1)
=> m = (4-1) / (1-1)
=> m = 3/1 = 3
