Jeremy performs the same operations on four values for x. He records each resulting y-value in a table, as shown below.
Which equation shows the operations Jeremy performs on x to get y?
х
у
5
2
4
13
21
6 8
29
y = 3x - 1
y = 2x + 1
y = 4x-3
y = x + 3

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
