The graph at the right shows Lanna’s total distance in miles for each day she is training for a marathon. Her friend, Sam, has a distance that can be represented by the function y = 4x, where y
is the number of miles ran and x is the number of days.
Which person is running more per day? How much are they running? The graph at the right
shows Lanna’s total distance in miles for each day she is training for a marathon. What is her
distance on day 10?
How many miles will Sam run by day 10?
How many miles will Lanna run by day 10?

Which situation could best be represented by this linear equation? 24x + 38y = 520 > if x represents the number of bracelets and y represents the number of rings, there were 24 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets and y represents the number of rings, there were 38 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets sold at $24 each and y represents the number of rings sold at $38 each, the total sales were $520 if x represents the number of bracelets and y represents the number of rings, there were 520 bracelets and rings sold. bracelets were $24, and rings were $38. e
