A graph is a picture that uses lines or curves to show the relationship between numbers or measurements that change. So, the graph in this problem indicates the number of handbags that Mandy made in one day. A variable is a quantity that may change according to the context of a mathematical problem or experiment. In this problem, we have two variables that are:
x = Time
y = Number of Handbags
<h2>2. Relationship between variables</h2>
As we said, this graph shows the Mandy's Handbags. From the graph, we can see that the number of handbags increases constantly at a regular interval. Until the time when he stopped making new handbags for the day. It is important to say that<em> time</em> is the independent variable while <em>the number of handbags</em> is the dependent variable, which is dependent on time.
