## Which design element is used to convey smoothness or roughness in a design?

Texture

**Which of the following is an element of design?**

Elements of design are seven in number, they include: shape, line, form, point, color, texture and space. These seven elements are the foundational building blocks use in design.

**What is line in design elements?**

Line is probalby the most fundamental of all the elements of design. A more usable deifnition might be that line is the path of a dot, point etc. through space and that is always has more length than thickness. Lines are not all the same, especially in art.

### What are 5 basic kinds of lines?

There are 5 main types of lines in art: vertical lines, horizontal lines, diagonal lines, zigzag lines, and curved lines. Other types of lines are simply variations of the five main ones.

**How do you use different kinds of lines?**

Types of lines

- Contour lines are used to define edges.
- Dividing lines can also define edges, but what distinguishes them from contour lines is they divide space.
- Decoration lines are used to embellish an object.
- Gesture lines are quick and rough continuous lines used to capture form and movement.

**What are the two kinds of line?**

How many types of lines are there? There are two basic lines in Geometry: straight and curved. Straight lines are further classifies into horizontal and vertical. Other types of lines are parallel lines, intersecting lines and perpendicular lines.

#### Is a horizontal line positive or negative?

The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0). because division by zero is an undefined operation.

**What is the equation of any horizontal line?**

Horizontal lines have a slope of 0. Thus, in the slope-intercept equation y = mx + b, m = 0. The equation becomes y = b, where b is the y-coordinate of the y-intercept.

**What is the slope of any horizontal line?**

Slope of a horizontal line. When two points have the same y-value, it means they lie on a horizontal line. The slope of such a line is 0, and you will also find this by using the slope formula.

## How do you write an equation for a vertical and horizontal line?

Horizontal lines go left and right and are in the form of y = b, where b represents the y-intercept, while vertical lines go up and down and are in the form of x = a where a represents the shared x-coordinate of all points. All you need to do is remember these.

**How do you know if a slope is vertical or horizontal?**

Note that when a line has a positive slope it rises up left to right. Note that when a line has a negative slope it falls left to right. Note that when a line is horizontal the slope is 0. Note that when the line is vertical the slope is undefined.

**What is the slope when the line is vertical?**

The slope of a line is change in Y / change in X. The slope of a horizontal line = 0, not undefined. The slope of a vertical line = undefined.

### Do parallel lines have the same slope?

As mentioned above, parallel lines have the same slope. So, if we know the slope of the line parallel to our line, we have it made.

**Is a slope of 0 linear?**

A zero slope means there is no change in the y -coordinates as the x -coordinates change, so this is a horizontal line.
