Answer:
B. Memphis is the only city whose highest temperature decreases.
Step-by-step explanation:
Let's analyse each statement looking at the graph given to see how true it is or not:
A. "The initial high temperature in Louisburg is lower than it is in Memphis."
Initial temperature is the y-intercept, that is, it is the point at which the line intercepts the y-axis.
Therefore, the city that has the greatest initial high temperature is Louisburg, which has a blue line labelled l. As you can see, the y-intercept has greater than every other city.
Therefore, Statement A is NOT TRUE.❌
B. "Memphis is the only city whose highest temperature decreases."
The line of Memphis slopes downwards from the left to our right. This shows a decrease in the highest temperature of Memphis. The line of every other city is either horizontal or slopes upwards.
Therefore, Statement B is TRUE.✅
C. "Louisburg always has the highest temperature."
The line of the graph of New Orleans shows that it's highest temperature exceeds that of others. As you can see, the line surpasses that of the rest three. So, Louisburg does not always have the highest temperature.
Therefore, Statement C is NOT TRUE.❌
D. "The high temperature in Phoenix rose faster than the high temperature in New
Orleans."
The slope of the line of New Orleans is more steeper than that of Phoenix. So, New Orleans high temperature rise faster compared to that if Phoenix.
Therefore, statement D is NOT CORRECT.❌
