just substitute the x and y values for the numbers on the tables. What i did was line up all the x values and do trial and error. The answers are:
table 1: y= -2x + 2
table 2: y = 5x + 2
table 3: y = 5/2x + 2
table 4: y = -3x + 2
table 5: y = -3/2x + 2
table 6: y=- x + 2
table 7: y= x + 2
table 8: y = -5x + 2
table 9: y = -5/2x + 2
table 10: y = 2x + 2
