Yes, y varies directly with x in this table.
The equation for the direct variation is y = kx, where k is the constant of variation.
Using the data points (40, 32) and (28, 16), we can find the value of k.
k = y/x = 32/40 = 16/28 = 0.8
Therefore, the equation for the direct variation is y = 0.8x.
For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation.
x - y:
40 - 32
28 - 16
16 - 12
