Step-by-step explanation:
Answer:
x and y do not show direct variation.
Step-by-step explanation:
The formula for direct variation is
y = kx Divide each side by y
k = y/x
k should have the same value for every point except, of course, (0,0)
For the first point,
k = 2/(-1) = -2
For the third point,
k = 2/1 = 2
The values of k are different, so x and y <em>do not</em> show direct variation.
0.5(y + 3.3)
The product of 0.5 and the sum of y and 3.3.
0.5 times the sum of y and 3.3
