How do you find the y-axis of a line?

To find the y-intercept of a line, substitute 0 for x into the equation and solve for y. You can use the intercepts to graph the line. The graph of 2x + 3y = 12 crosses the x-axis at (6, 0), so its x-intercept is 6. The graph of 2x + 3y = 12 crosses the y-axis at (0, 4), so its y-intercept is 4.

What does the y-axis show on a graph?

The y-axis is like a vertical ruler. It shows you where an object on a Cartesian plane, a two-dimensional mathematical graph, is in the y (vertical) direction. It is also the starting, or zero, point for measuring how far a point is to the right or left (horizontally) on a graph.

Is the line y 0 the y-axis?

Note: There are chances that you might interpret the line y = 0 as y-axis. This is wrong. The line y=0 simply implies that for all the points (x, y) in the x-y plane, the y coordinate is always 0, which means that the line y=0 represents x-axis.

What is it called when the y-axis is 0?

The vertical axis is called the y-axis. The point at which the two axes intersect is called the origin. The origin is at 0 on the x-axis and 0 on the y-axis.

Is the Y coordinate of the point where the graph crosses the y axis?

The y-intercept is the point, (0, b), where the graph crosses the y-axis. The x-intercept occurs when y is zero. The y-intercept occurs when x is zero.

What is the y-coordinate of?

y-Coordinate. A y-coordinate is the second element in an ordered pair. When an ordered pair is graphed as the coordinates of a point in the coordinate plane, the y-coordinate represents the directed distance of the point from the x-axis. Another name for the y-coordinate is the ordinate.

Where is the Y coordinates on a graph?

The y-coordinate of a point is the value that tells you how far from the origin the point is on the vertical, or y-axis. To find the y-coordinate of a point on a graph: Draw a straight line from the point directly to the y-axis. The number where the line hits the axis is the value of the y-coordinate.

What is XY in algebra?

In algebra, when we preceed a variable by a number, we multiply. In the same way, xy means multiply the variable x by the variable y and 7xy means multiply the variable x by the variable y and multiply the whole thing by 7.

What is an XY coordinate?

An x-y axis, also known as a cartesian coordinate system or a coordinate plane, is a two-dimensional plane of points defined uniquely by a pair of coordinates. Those coordinates measure the distance of the point from the x-axis and the y-axis.
