They ALL have the same value.
Answer:
B. y = x +3
Step-by-step explanation:
The fastest way to find this answer is to substitute offered values of x and y into the given equations to see if they are true.
<h3>Substitution</h3>
Using the first line in the table, (x, y) = (2, 5), we have ...
A 5 = 2(2) . . . . false
B 5 = 2 +3 . . . . true
C 5 = 3(2) . . . . false
D 5 = 2 +1 . . . . false

<em>Additional comment</em>
Checking answer choices against the problem statement is one of many possible strategies for answering multiple-choice questions.
To find this out the easy way, add up all the numbers and an answer, then divide by 4.
59 + 64 + 68 + 63.67 = 254.67
254.67/4 = 63.66
A is not correct.
59 + 64 + 68 + 65.25 = 256.25
256.25/4 = 69.25
B is not quite correct.
59 + 64 + 68 + 75 = 266.
266/4 = 66.5
C is not correct.
59 + 64 + 68 + 89 = 280
280/4 = 70.
D.) is the correct answer.
I hope this helps!
