Find the constant (k) of proportionality in the table. What equation represents the table?

X 2 3 8 10
Y 8 12 32 40

To find the constant of proportionality, we need to find the ratio of Y to X in each pair of values.

For the first pair: Y/X = 8/2 = 4
For the second pair: Y/X = 12/3 = 4
For the third pair: Y/X = 32/8 = 4
For the fourth pair: Y/X = 40/10 = 4

Since the ratio Y/X is constant at 4, the constant of proportionality is 4.

The equation that represents the table is Y = 4X.
