Question

# The table shows the temperature and number of tickets sold at a movie theatre . Construct a scatter plot of the data. Is there a relationship between temperature and the number of tickets sold?Determine the scales and plot the points.

Hint:

## The correct answer is:

### Step 1 of 3:Let Temperature be taken on the x- axis and the tickets sold be taken on the y- axis.Then the corresponding coordinate points are;(40,120),(45,100),(50,125),(55,105),(60,90),(65,105),(80,60),(85,55),(90,60),(95,50)Step 2 of 3:Plot the points on the graph to get the scatter plot. Step 3 of 3:Analyzing the graph, it is clear that as the temperature increases, the tickets sold decrease. That is, there exists an inverse relation among the variables.These show the existence of a negative linear relationship.The scales 1 interval =100 units. .

A scale is a system of marks at fixed intervals, which define the relation between the units being used and their representation on the graph
