Answer:
(0 , 1), (4, 9).
Step-by-step explanation:
y = x2 – 2x+1
y = 2x+1
Substitute y = 2x + 1 into the first equation.
2x + 1 = x^2 - 2x + 1
x^2 - 2x - 2x = 0
x^2 - 4x = 0
x(x - 4) = 0
x = 0, 4.
When x = 0, y = 1.
When x = 4, y = 8 + 1 = 9.
Answer: y= 0.25x + 3.75
Step-by-step explanation:
(x-4y) (x+7y) is the answer
