Answer:
1. B and E
2. B
Step-by-step explanation:
1. Looking at the line, let's try to establish a relationship between x and y. Take one point (12, 80) and divide y by x:
80 / 12 = 20 / 3
Similarly, if we take (3, 20), we get the same relationship:
20 / 3 = 20 / 3
That means we need to select an ordered pair that follows this relationship:
A. (14, 100) ⇒ 100 / 14 = 50 / 7 --- wrong
B. (15, 100) ⇒ 100 / 15 = 20 / 3 --- correct
C. (16, 100) ⇒ 100 / 16 = 25 / 4 --- wrong
D. (16, 120) ⇒ 120 / 16 = 15 / 2 --- wrong
E. (18, 120) ⇒ 120 / 18 = 20 / 3 --- correct
The possible answers are B and E.
2. Let's say Maya sells b bracelets. That means that she makes 3 * b = 3b dollars for these b bracelets. Look at the answer choices to see which one will have 3 in the x-coordinate and a multiple of 3 in the y-coordinate:
A. (3, 5) ⇒ 5 isn't a multiple of 3, so wrong.
B. (3, 9) ⇒ 3 is the x-coordinate and 9 = 3 * 3, so this is correct.
C. (3, 7) ⇒ 7 isn't a multiple of 3, so wrong.
D. (2, 3) ⇒ 3 isn't even the x-coordinate, so wrong.
The correct answer is thus B.
