To find the constant of proportionality in the table, we need to select two points and determine the ratio of y values to x values. Let's use the first two points:
Point 1: (1, 4)
Point 2: (2, 8)
The ratio of the y values to the x values is 8/2 = 4.
This means that k = 4.
The equation that represents the table is y = 4x, which is option B.
Find the constant (k) of proportionality in the table. What equation represents the table?
A. y = 1/4 x
B. y = 4x
C. y=8x + 2
D. y=1/8x
