Number lines
Contour lines are used when you have spatial data, with the x,y values identifying a particular point and z is the value at that point. It could be elevation above sea level, temperature, pressure or any other measurable property. Contour lines identify where the data suggests equal values should exist. On an elevation map, contour lines show the elevation of equal values points. A 50 ft contour line would go through all points where the data suggest should be at 50 ft elevation. See related links.

Points cannot be parallel to other points. A straight line joining two points is parallel to a straight line joining another pair of points if the gradient (slope) of the two lines is the same.
The graph is called the 'line of best fit'
a line graph.
a graph that uses two lines connected by points to show value
the points on a bar graph are not connected to each other.
Scatter plots show how much one variable is affected by another,A graph that uses points connected by lines to show how something changes in value
A broken line graph shows information by plotting points of information on the graph and are connected with a line. This is used to show continuous data.

Contour maps show the shape and elevation of the land by using contour lines to represent points of equal elevation. This allows viewers to visualize topography and understand the natural landscape of a given area.
