A linear equation exist for the following sets of ordered pairs {(-1,1), (0,3), (-1/3, 7/3)} the rule for this equation states that y is three more than twice x set up the linear equation that satisfies the rule and use the set of ordered pairs to prove that your equation satisfies the set of coordinates. I need this answered ASAP

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
