To determine the constant of proportionality, we can choose two points from the table and divide the corresponding y-values by the x-values. Let's choose the points (9, 63) and (4, 28):
k = 63 / 9 = 7
k = 28 / 4 = 7
Therefore, the constant of proportionality (k) is 7.
The relationship between y and x is y = 7x.
Determine the constant of proportionality (k) for the table and write the relationship between y and x.
x: 9 4 2 11
y:63 28 14 77
