Determine the constant of proportionality (k) for the table and write the relationship between y and x. (1 point) Responses k = 17 k = 1 seventh k = −17 k = negative 1 seventh k = -7 k = -7 k = 7 k = 7 Skip to navigation
X - 9 4 2 11
Y - 63 28 14 77
To determine the constant of proportionality (k), we can use the formula: k = y/x.
For the first pair of values (9, 63):
k = 63 / 9
k = 7
For the second pair of values (4, 28):
k = 28 / 4
k = 7
For the third pair of values (2, 14):
k = 14 / 2
k = 7
For the fourth pair of values (11, 77):
k = 77 / 11
k = 7
Since the values of k are consistently 7 for all pairs of values, the constant of proportionality is k = 7. Therefore, the relationship between y and x is:
y = 7x
