Answer:
44 52 95 76 13 94 83 72 55 81 22 25 64
The mean is: 59.7
65 72 48 63 68 59 68 62 75 79 81 72 64
The mean is: 67.4
It does represent a direct variation.
Direct variation: y = kx
y varies directly with x
Your equation 2y = 5x + 1 is in the form of y = kx but we need to divide out the 2 from 2y so we have the following
2y = 5x + 1
2y / 2 = 5 x/ 2 + 1/2
y = 5x / 2 + 1/2
y = kx
k = 5/2
k = constant of variation = 5/2
