Question

kak tolong pakem cara nya​

Answer 1

f(x) = ax + b

f(3) = 3a + b = 2

f(-2) = -2a + b = -8

.

• Nilai a

3a + b = 2

-2a + b = -8

___________-

5a = 10

a = 2

• Nilai b

→ -2a + b = -8

→ b = -8 + 2a

→ b = -8 + 2(2)

→ b = -8 + 4

→ b = -4

• Nilai a + b

→ a + b

→ 2 + (-4)

→ 2 - 4

→ -2
