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.
