Determine whether the graph represents a proportional relationship.

a graph is shown. the x-axis is labeled from 0 to 16. the y-axis is labeled from 0 to 16. four points are shown on the graph on ordered pairs 0, 0 and 1, 3 and 2, 6 and 3, 7. these points are joined by a line. the label on the x-axis is number of pans. the title on the y-axis is number of cakes.

yes, it is a proportional relationship because the graph goes through the origin
yes, it is a proportional relationship because the graph is a straight line
no, it is not a proportional relationship because the graph is not a straight line
no, it is not a proportional relationship because the graph does not go through the origin

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
