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

y = 1/4 x

y = 4x

y= 8x + 2

7 = 1/8x

Answer 1

To find the constant (k) of proportionality in the table, we can choose two values from the table and use them in the equation y=kx.

Let's choose x=2 and y=8.
8 = k*2
k = 8/2
k = 4

Therefore, the constant (k) of proportionality is 4 and the equation representing the table is y = 4x.
