Hidden edges
Because the line goes on forever in both directions.
To measure an angle of elevation using a protractor, first position the protractor so that its center point aligns with the vertex of the angle you are measuring. Ensure the baseline of the protractor is level with the horizontal line from the vertex. Look up towards the point creating the angle of elevation and read the measurement on the protractor where the line of sight intersects the degree scale. This reading indicates the angle of elevation from the horizontal to the line of sight.
To write the number 1, start by drawing a straight vertical line from top to bottom. It should be a tall, thin line with no curves or loops. You can also use the numeral "1" to represent the number.
To make a 270-degree angle, start by drawing a line segment horizontally to the right. From the endpoint of this line, use a protractor to measure 270 degrees in the clockwise direction. Mark the point where the 270-degree line intersects, and then draw a line from the original endpoint to this new point. The angle formed between the original line and the new line is a 270-degree angle.
A protractor.
By drawing the number line and label it.
Measuring stuff or drawing a straight line.
you use a broken line graph usually for showing continuous data (data with growth over time)
So the drawing is a very fine line and easy to rub out?

Topography
One important element of drawing is understanding and practicing the use of line work. Lines can convey shape, texture, and depth, and mastering different types of lines can greatly enhance the impact of a drawing.
You would use a broken bar graph, when grouping and gathering information. You would use straight, slanted, or vertical lines and showing points with dots. A broken bar graph is just like a line graph.
The line that forms the edge of a figure is an edge line. Which forms the figure the has been drawn. You use this line to define a drawing or a figure.
To measure an angle of elevation using a protractor, first position the protractor so that its center point aligns with the vertex of the angle you are measuring. Ensure the baseline of the protractor is level with the horizontal line from the vertex. Look up towards the point creating the angle of elevation and read the measurement on the protractor where the line of sight intersects the degree scale. This reading indicates the angle of elevation from the horizontal to the line of sight.
A single broken yellow line mean when safe to do so that will not interfear with other traffic, go pass the line and pass the vehicle on the left side and use that lane only for passing.
