Question
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 = k = -7 k = -7 k = 7
x=9, 4, 2, 11
y=63, 28, 14,77
x=9, 4, 2, 11
y=63, 28, 14,77

To determine the constant of proportionality (k), we need to calculate the ratio of y to x for each pair of values in the table:
y/x = 63/9 = 7
28/4 = 7
14/2 = 7
77/11 ≈ 7
The ratio is the same (7) for all pairs of values, so the constant of proportionality (k) is 7.
Therefore, the relationship between y and x can be expressed as y = 7x.
y/x = 63/9 = 7
28/4 = 7
14/2 = 7
77/11 ≈ 7
The ratio is the same (7) for all pairs of values, so the constant of proportionality (k) is 7.
Therefore, the relationship between y and x can be expressed as y = 7x.
