Find the constant (k) of proportionality in the table. What equation represents the table?
(1 point)
Responses
y = 1/4 x
y = 1/4 x
y = 4x
y = 4x
y=8x + 2
y=8x + 2
y=1/8x
To find the constant of proportionality in the table, we can pick any two points and use the formula k = y/x.
Let's use the points (1, 1) and (2, 2) from the table:
k = 1/1 = 1 = 2/2
Therefore, the constant of proportionality in the table is 1. The equation that represents the table is y = 1x or simply y = x.
