Question

What is the equation for the constant of proportionality that

matches the table?

y = 9x

y=18x

y = Ox

y = x

Answer 1

y=9x

Explanation:

For these x's and y's, we can notice that y is always equal to 9 times the value of x. 0 equals 9 * 0, 9 equals 9 * 1, 18 equals 9 * 2, 27 equals 9 * 3, and 36 equals 9 * 4.

We have just shown that y equals 9 times x, which is just y=9*x, or y=9x.
