Answer:
Explanation:
y = kx
proportionality constant = k = y/x
A. k = y/x = 7/2 = 3.5 (you can plug in any x,y pair from the table and will get the same answer, 3.5)
B. k = y/x = 12/3 = 4 (you can choose any point on the line)
C. k = y/x = 2.75 (same as the slope of the line)
D. k = y/x = earnings/games = 65/5 = 13
E. k = y/x = 12/3 = 4 (you can plug in any x,y pair from the table and will get the same answer, 4)
