what direction is x and y?

X and Y Axis The left-right (horizontal) direction is commonly called X. The up-down (vertical) direction is commonly called Y.

Are x and y both positive? This just means that x and y have the same sign. They're either both positive or both negative.

the x-axis is the point (x,-y). Reflect over the y-axis: When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed).

The graphical concept of x- and y-intercepts is pretty simple. The x-intercepts are where the graph crosses the x-axis, and the y-intercepts are where the graph crosses the y-axis. ... In the same way, the x-axis is also the line "y = 0". Then, algebraically, an x-intercept is a point on the graph where y is zero, and.

it's always Y against X, because Y is the dependent variable. im varying the current hence its on the y axis i just cant remember how to put it in words it is supposed to go in a specific order determined by which is on each axis.

The terms vertical and horizontal often describe directions: a vertical line goes up and down, and a horizontal line goes across. You can remember which direction is vertical by the letter, "v," which points down.

If you look at a coordinate plane the x axis measures left and right and the y axis measures up and down. ... So the Z axis is up and down movement, the Y axis is foreward and backward movement, and the X axis is side to side movement. The Z rotation measures how the controller is tilted in 3D space.

The coordinate plane has two axes: the horizontal and vertical axes. These two axes intersect one another at a point called the origin. Learn about the ordered pair that indicates the origin and its location in the coordinate plane by watching this tutorial!

Directions are indicated on the maps by the North-South line, with the arrow head pointing towards the North. If the north-south line with the arrow is not drawn on the map, then the top of the map is taken as the north and the bottom of the map as the south; the right is the east and the left is the west direction.

The formula y=mx+b describes a line in the Cartesian Coordinate System. ... You're right about m being the slope and b being the y-intercept (which is the point where the line crosses the y-axis). x and y are the coordinates of the points on the line. They are both variables.

One can start off by designating the vertical direction, usually labelled the Y direction. ... A vertical line is any line parallel to the vertical direction. A horizontal line is any line normal to a vertical line. Horizontal lines do not cross each other.

In the coordinate plane, all vertical lines are parallel to the y-axis, and are parallel to one another. But, the slopes of vertical lines are undefined since vertical lines have no "run".

How to Find the Direction Cosine? The direction cosine of the vector can be determined by dividing the corresponding coordinate of a vector by the vector length. The unit vector coordinates is equal to the direction cosine.

The point where the x-axis and y-axis intersect is called the origin. The numbers on a coordinate grid are used to locate points. ... The order in which you write x- and y-coordinates in an ordered pair is very important. The x-coordinate always comes first, followed by the y-coordinate.

The direction of a relationship tells whether or not the values on two variables go up and down together. Direction is indicated by a positive or a negative sign. If two variables are positively correlated, then as the values on one variable go up, so do the values on the other variable.
