Converting point-slope use the point-slope form of a line to write the equation of a line that has a slope of 2 and passes through the point (–4, 3). write the equation in slope-intercept form. choose the equation of the line.
a) y = 2x – 7
b) y = 2x + 11
c) y = –4x + 14
d) y = 3x +14

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.
