Line

A straight line moves in one direction without bending. Exam tip: identify straight line by simple direction.

The edge of a circle changes direction continuously, so it is an example of a curved line. A stair strip and a table edge are generally straight lines, while a square window is made of straight line segments meeting at corners. Exam tip: a curved line bends smoothly without forming sharp angles.

A horizontal line moves left to right like the ground. Exam tip: remember horizontal from horizon.

A vertical line runs straight from top to bottom, so option A is correct. A line running from left to right is horizontal, while a slanting line is diagonal. Exam tip: remember a vertical line as the upright line of a pole or a tree.

A diagonal line is a straight line that is neither horizontal nor vertical; it slopes in one direction. Therefore, a slanting line is correct. A curved line changes its direction and is not straight. Exam tip: a straight line drawn from one corner towards another at a slant is usually diagonal.

A wavy line bends smoothly up and down repeatedly, so it looks like a water wave. A straight stick represents a straight line, while a square box is made of angular lines. Exam tip: identify a wavy line by its smooth, repeated up-and-down curves.

A zigzag line changes direction repeatedly through sharp angles, producing pointed turns. Therefore, sharp angular turns are its main feature. A line with gradual rounded bends is a curved line, not a zigzag line. Exam tip: identify a zigzag line by repeated pointed turns like ‘V’ or ‘W’.

A thick line stands out more clearly in an artwork, so it creates an effect of emphasis, visual weight, and strength. Delicacy and lightness are generally conveyed by thin lines. Exam tip: greater line thickness usually suggests greater emphasis and visual weight.

A thin line gives a light and delicate effect. Exam tip: remember thin line with delicate effect.

A broken line is formed by separate small marks or segments with gaps between them. A continuous unbroken mark forms a continuous line, not a broken line. Exam tip: identify a broken line by looking for spaces between its parts.

A continuous line is drawn in one flow without breaking or leaving gaps in between. Therefore, ‘Moving forward without a break’ is correct. A line with several gaps is a broken or discontinuous line, not a continuous line. Exam tip: remember that ‘continuous’ means ‘unbroken’.

An outline is the line drawn around a shape to define its boundary and outer form. Filling shaded areas creates depth or tone; it is not the function of an outline. Exam tip: remember ‘outline’ as the outer boundary of a shape.

A contour line shows the outer boundary, shape, and edges of an object. It helps distinguish the object from the space around it. The width of a picture frame does not describe an object's outline. Exam tip: remember contour as the outer outline of an object.

An implied line may not be visible but guides the eye. Exam tip: treat implied line as invisible guide.

A line can guide the viewer’s eye in a particular direction and help create outlines or shapes of objects. Therefore, option A is correct. Increasing paper weight, indicating colour prices, and cleaning a brush are not artistic functions of line. Exam tip: Remember direction, outline, shape, and texture as key uses of line.

The thickness or thinness of a line is called line weight. Different line weights, such as thick and thin lines, can create emphasis, depth, or a sense of distance in an artwork. Colour temperature refers to the warm or cool effect of colours, not the thickness of a line. Exam tip: associate thickness, boldness, or thinness of a line with line weight.

Repeated lines can create surface effect. Exam tip: remember repeated lines for texture.

Hatching uses closely spaced lines drawn in one direction to show shading, depth, or texture. Areas appear darker when the lines are placed closer together. A pattern made with round dots is not hatching. Exam tip: identify hatching by parallel or same-direction lines.

In cross hatching lines cross over one another. Exam tip: connect cross with crossing lines.

A light line is produced when the pencil or drawing tool touches the paper gently. Pressure means the force used while drawing. When the pressure is small, less graphite or colour reaches the paper, so the mark appears pale and delicate. This is useful for outlines, first sketches, construction lines, and areas that should not look heavy. Therefore, the correct choice is B, less pressure. Very high pressure would make the line darker, thicker, or more strongly impressed in the paper. Tearing paper and drying colour do not control the darkness of a drawn line.

To solve this, connect the strength of the hand with the darkness of the mark. A soft touch generally gives a light line, while pressing harder gives a dark line. The exact darkness can also depend on the tool and paper, but among the given choices only less pressure directly produces the required result. Thus the supplied answer B is accurate and follows the basic principle of line control.
