What is the fact family for 2, 10, 20

the fact family for this problem is 1,2, because 1 times any number equals that number

and since

2 x 1 = 2

2 x 5 =10

2 x 10 = 20

those are the two numbers in the fact family (1,2)

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)
