D) is correct.
Looking at the graph, it goes through the point (2, 200) and is very near the point (3, 300). This means it increases by nearly 100 every month; this tells us how much she saves each month.

Step-by-step explanation:
Answer: (C) x² - 4x + 5 = 0
<u>Step-by-step explanation:</u>
x = 2 ± i
⇒ x = 2 + i and x = 2 - i
⇒ x - (2 + i) = 0 and x - (2 - i) = 0
0 = (x - 2 - i)(x - 2 + i)
= x(x - 2 + i) -2(x - 2 + i) -i(x - 2 + i)
= x² - 2x +xi -2x + 4 <u>- 2i</u> -xi <u>+ 2i</u> - i²
= x² - 4x + 4 - i²
= x² - 4x + 4 -(-1)
= x² - 4x + 5

Answer: B
Explanation:
The slope from (0, 0) to (1, 4) is a rise of 4 and a run of 1, thus, m = 4/1 = 4
