A sketch graph is a visual representation of data plotted on a coordinate plane. It is used to show the relationship between two variables and to identify patterns or trends in the data.
To read a sketch graph, start by looking at the horizontal and vertical axes. These represent the two variables being compared. Then, locate the data points plotted on the graph and connect them with a line or curve. Finally, analyze the shape and direction of the line or curve to interpret the data.
The blue highlighted part on a sketch graph typically represents a specific area or range of data that is being emphasized. This could be a particular section of the graph that is of interest or importance, or it could be used to show a specific trend or pattern within the data.
To determine the slope of a sketch graph, you can use the rise over run method. This involves selecting two points on the graph and calculating the change in the y-values (rise) over the change in the x-values (run) between those two points. The slope is then represented as a ratio, such as 2:1 or 1/2, or as a decimal or percentage.
Some common mistakes when interpreting sketch graphs include misreading the axes, incorrect labeling of data points, and not considering the scale or units of measurement used on the graph. It is important to pay attention to all the details on a sketch graph and to double-check your interpretations to avoid these errors.
