Graphing x = 3 is a matter of drawing a vertical line on the Cartesian plane. For any equation x = n, where n is any real number, the resulting graph is a vertical line crossing the x-axis at the value of n. To graph the given equation, draw the Cartesian plane, plot the coordinates of the graph, and draw a line through it.
Full Answer >Several types of graphs are used for displaying information in mathematics including the bar graph; pie chart or circle graph; histogram; stem and leaf plot; dot plot; scatter plot; and time-series graphs. The type of graph chosen depends on whether the data is quantitative, qualitative or paired.
Full Answer >Bar graphs, or bar charts, are a way of representing data visually; printable bar charts enable people giving presentations to convey digital information on paper. They are similar to line charts but are often used to show discrete components instead of how something changes over time.
