This is an interactive math test in which students will interpret a line graph in each case in order to attribute values as per the question asked. After finding the value, simply submit your answer and find out if you got it correct. Same as bar graphs, linear graphs visually represent data in a raw form which might have been represented on a table or in a pictograph. A typical question may be like there is a graph that shows the number of visitors to a park and then the child is supposed to interpret what the graph is actually depicting and then needs to answer the questions with relevant details.

What is linear graph and how to use them?

A linear graph is a way of showing a relationship between two different things using a line. The line on a linear graph is always straight, and it helps us to see how one thing (known as the independent variable) is affected by another thing (known as the dependent variable).

For example, let’s say that we want to make a graph to show how the number of ice cream cones sold at a store changes depending on the temperature outside. The temperature would be the independent variable, and the number of ice cream cones sold would be the dependent variable. We could make a linear graph with temperature on the x-axis (horizontal) and the number of ice cream cones sold on the y-axis (vertical).

To make this graph, we would first gather data by measuring the temperature and the number of ice cream cones sold for several days. Then we would plot these points on the graph. Each point on the graph would represent one day, with the temperature on the x-axis and the number of ice cream cones sold on the y-axis. We would then draw a line that goes through as many of these points as possible. This line is called the “line of best fit” and it helps us to see the overall pattern in the data.

The slope of the line tells us how steep the line is. A steep line means that the number of ice cream cones sold changes quickly as the temperature changes. A shallower line means that the number of ice cream cones sold changes more slowly as the temperature changes.

The y-intercept tells us the value of y when x is equal to zero, It means the number of ice cream cones sold when the temperature is zero degree.

We can also use linear graphs to make predictions. For example, if the temperature is 30 degrees outside, we can use the line of best fit to estimate how many ice cream cones will be sold that day.

Linear graphs are just one type of graph that we can use to show relationships between two things. Other types of graphs include bar graphs, pie charts, and scatter plots. Each type of graph is useful in different situations, depending on what type of data we have and what we want to show with the graph.

Overall, Linear Graph is a great tool for kids and adults to understand the relationship between two different variables and it helps to make predictions. It helps to visualize the data in a meaningful way and make better decisions in many fields like finance,economics, science and many more.
