Question

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

x 2,3,8,10
y 8,12,32,40

Answer 1

To find the constant of proportionality, we can divide the y-values by the corresponding x-values:

y/x = 8/2 = 4
y/x = 12/3 = 4
y/x = 32/8 = 4
y/x = 40/10 = 4

So, the constant of proportionality (k) is 4.

The equation that represents the table is y = 4x.
