A horizontal line parallel to x axis (slope = 0)
a vertical line at x=3
The x-intercept of a line is the point at which the line crosses the x-axis.

On the Cartesian plane the x line is the horizontal axis and the y line is the vertical axis.
A horizontal line parallel to x axis (slope = 0)
The kind of function without an X variable.Y = 4is a horizontal line.
A line which is the reflection of the original in y = x.
vertical lines!
A vertical line intercepting the x-axis at 9 with an undefined slope.
Undefined slope.
A horizontal line, such as Y = 3, has a slope of zero.Slope is the limit, as delta x approaches zero, of delta y / delta x.
A line that is perpendicular to (at right angles with) the x-axis.
An Area chart. It fills the space below the line until the next line or x-axis with a solid fill colour.
if we are considering the ascending line as which increases as the x & y co-ordinate increases then it must have a posetive slope.
Imagine the set up: line 1 X line 2 X X line 3 X X X line 4 X X X X line 5 (empty) Move the pin from line 1 to the centre of line 5. line 1 (empty) line 2 X X line 3 X X X line 4 X X X X line 5 X Now move the 2 outer pins on line 4 to the outer position on line 2 line 1 (empty) line 2 X X X X line 3 X X X line 4 X X line 5 X And there you go. Except the spacings I used weren't saved. I hope you get the idea though!
A line with the equation:x = a constant valueis a vertical line. Examples of such a line are x = 3, x = 5, x = 10, x = -4.The slope of a vertical line is infinite.
