-a + b = -5
2a + b = 1
__________-
-3a = -6
a = 2
b = -5 + a
b = -5 + 2
b = -3
Persamaan fungsi
→ f(x) = ax + b
→ f(x) = 2x + (-3)
→ f(x) = 2x - 3
Tabel pada gambar.
Daerah bayangan
Ada pada gambar
f(x) = 2x - 3
y = 2x - 3
Titik koordinat
y = 2(0) - 3
y = -3
(0,-3)
0 = 2x - 3
-2x = -3
x = 3/2
(3/2, 0)
