Answer:
B
Step-by-step explanation:
y = x² → (1)
y = 3x - 2 → (2)
substitute y = x² into (2)
x² = 3x - 2 ← subtract 3x - 2 from both sides
x² - 3x + 2 = 0 ← in standard form
(x - 1)(x - 2) = 0 ← in factored form
equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x - 2 = 0 ⇒ x = 2
substitute these values into (2) for corresponding values of y
x = 1 : y = 3(1) - 2 = 3 - 2 = 1 ⇒ (1, 1 )
x = 2 : y = 3(2) - 2 = 6 - 2 = 4 ⇒ (2, 4 )
