To find the constant of proportionality, we can choose two points from the table and calculate the ratio of y to x. Let's use the points (2, 8) and (10, 40):
(8/2) = 4
(40/10) = 4
Since the ratio is the same for both pairs of points, the constant of proportionality (k) is 4.
Therefore, the equation that represents the table is y = 4x.
Find the constant (k) of proportionality in the table. What equation represents the table?
x/2/3/8/10
y/8/12/32/40
