Tolong jawab...............

2.a garis itu melalui titik (1,1) dan (5,3)
Persamaan garisnya : (p-1)/(3-1) = (t-1)/(5-1)
(p -1)/2 = (t-1)/4
4p - 4 = 2t - 2
4p - 2t - 2 = 0
b. Nilai t ketika p = 0
4(0) - 2t - 2 = 0
-2t = 2
t = -1
Nilai p ketika t = 11
4p - 2(11) - 2 = 0
4p - 24 = 0
4p = 24
p = 6
Semoga membantu.
