8. which graph below shows the rule: output = 2 times input? (1 point)

third graph

Step-by-step explanation: let output=y and input=x

we have to see the graph of y=2x i.e. y=0 when x=0

                                                     y=2 when x=1

                                                      y=4 when x=2

i.e. y increases rapidly as x increases

which is true for third graph

sorry, can't i suggest going to algebra.com
