What is the equation of the x axis

What is the equation of Y axis?

The equation of y-axis is x = 0, since, y-axis is a parallel to itself at a distance 0 from it. Let P (x, y) be any point on the y-axis. Then clearly, for all position of P we shall the same abscissa 0 or, x = 0. Therefore, the equation of y-axis is x = 0.

What is the equation of X axis in coordinate geometry?

Recall from the lesson on Vertical and Horizontal Lines that the equation for the x-axis is y=0, and the equation for he y-axis is x=0. So in other words, any point on the x-axis has a y coordinate of 0. And any point on the y-axis has an x coordinate of 0.

What is usually on the X axis?

Scientists like to say that the “independent” variable goes on the x-axis (the bottom, horizontal one) and the “dependent” variable goes on the y-axis (the left side, vertical one).

Is Y 0 the y axis?

Take a closer look, and you’ll see that the y-axis is also the line “x = 0”. In the same way, the x-axis is also the line “y = 0”. an x-intercept is a point on the graph where y is zero, and. a y-intercept is a point on the graph where x is zero.

What is y axis on a graph?

more The line on a graph that runs vertically (up-down) through zero. It is used as a reference line so you can measure from it. See: Coordinates.

What is y axis called?

Also called axis of ordinates. (in a plane Cartesian coordinate system) the axis, usually vertical, along which the ordinate is measured and from which the abscissa is measured. (in a three-dimensional Cartesian coordinate system) the axis along which values of y are measured and at which both x and z equal zero.

What is Y 0 on a graph?

If you know this, then you can simply just go ahead and draw a horizontal line through the y-intercept, in this case 0. Since the equation y = 0 has a y-intercept of 0, your graph is essentially the x-axis. The y-value is always 0.

What is the Y intercept in an equation?

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis. © 2000-2005 Math.com. All rights reserved.

Potential energy equation physics

What is potential energy physics? To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height. What is potential and kinetic energy? All forms of […]

Bonding energy equation

What is bond energy in chemistry? In chemistry, bond energy (BE), also called the mean bond enthalpy or average bond enthalpy is the measure of bond strength in a chemical bond. The larger the average bond energy, per electron-pair bond, of a molecule, the more stable and lower-energy the molecule. What are the units of […]
