Ms. Leeper gives her sixth- and seventh-grade students a geography test to decide who will represent her class in the school geography bee. The line plots below show the results of the test for her sixth-grade class and seventh-grade class, respectively.
The data for each grade have the same interquartile range (IQR). Which of the following best compares the two test score distributions?
A - The median score of the seventh-grade class is 2 points greater than the median score of the sixth-grade class. This difference is the same as the IQR.
B - The median score of the seventh-grade class is 2 points greater than the median score of the sixth-grade class. This difference is twice as much as the IQR.
C - The median score of the seventh-grade class is 3 points greater than the median score of the sixth-grade class. This difference is the same as the IQR.
D - The median score of the seventh-grade class is 3 points greater than the median score of the sixth-grade class. This difference is twice as much as the IQR.

Answer:
The first one is proportional and the second one is not. Because for the first one you can see that if you divide the number of pens by the cost you'll get the same answer for every single one. But for the second one if you divide the number of minutes by words typed you get a different answer for each one. You can also see if it's proportional or not if you draw it on the graph and it's a straight line. If it is the relationship is proportional if it isn't it's not proportional. Hope that makes sense :)
Determine whether the relationship between the two quantities shown in the table or graph is linear. If so, find the constant rate of change. If not, explain your reasoning. 1. SOLUTION: Analyze the table. The rate of change from 5 hours to 8 hours is or 3 cents per hour. This is the same as therate of change from 8 hours to 12 hours, or 3 cents per hour, and from 12 hours to 24 hours, or 3 cents per hour. So, the rate of change is a constant 3¢ per hour. ANSWER: Yes; the rate of change between cost and time for each hour is a constant 3¢ per hour. e i dont know if this is the answer to ur question but here u go

"Explain why the solution of a system of linear equations is the point of intersection of their graphs"
Can you please explain this to be in a simpler form?
Answers
Answer:
Step-by-step explanation:
The solution of a system of linear equations is the point of intersection of their graphs because the intersection represents the only x or y values that will satisfy both/all equations. The graph visually shows that the intersection of these equations is the only spot on the graph that all of the equations have in common. This means that only this spot will satisfy all equations. For example, the intersection may be (0,1); this means that for all equations an x value of 0 will always result in the y value of 1. However, an x or y value that satisfies one equation may not satisfy the others if they do not lead to the desired outcome.
