What points shown below are on the line given by the equation y equals 2x?
To determine which points are on the line given by the equation ( y = 2x ), you can substitute the x-coordinate of each point into the equation and see if the resulting y-coordinate matches the point's y-coordinate. For example, if you have the point (1, 2), substituting ( x = 1 ) gives ( y = 2(1) = 2 ), so this point is on the line. Repeat this process for each point to find which ones satisfy the equation.
How is a point in a coordinate grid represented?
It is represented in the form of (x, y) whereas x and y have given values
What does it mean to reflect a point across the x or y axis?
Reflecting a point P, in the x axis is finding another point Q such that they both have the same x-coordinate and that the y-coordinate of Q is the additive inverse of the y-coordinate of P. Thus, is P is 4.5 above the x-axis, then Q is 4.5 below it and if P is below, then Q is above by the same distance.Reflection in the y-axis is similar except that now it is the y-coordinate that remains the same and the x-coordinate that changes. If P was to the left then Q is to the right (and conversely).
What does y-coordinate mean in math?
In mathematics, the y-coordinate refers to the second value in an ordered pair (x, y) that represents a point's position in a Cartesian coordinate system. It indicates the vertical position of the point relative to the origin, where positive values are above the origin and negative values are below it. In a graph, the y-coordinate is plotted along the vertical axis.
What is the abscissa is positive and the ordinate is negative?
When the abscissa (x-coordinate) is positive and the ordinate (y-coordinate) is negative, the point lies in the fourth quadrant of the Cartesian coordinate system. This means the point has a location where it is to the right of the y-axis and below the x-axis. An example of such a point would be (3, -2).
What is the y-coordinate of the vertex of a parabola with the following equation?
The y coordinate is given below:

How can you name a point on a graph?
Compare it's position to the origin. The x coordinate is the number of units to the right of the origin. (If it is to the left of the origin the x coordinate is negative.) The y coordinate is the number of units above the origin. (If it is below, the y coordinate is negative.) The point is denoted (x,y) with the x coordinate in place of the x and the y coordinate in place of the y.

What is the y-coordinate of the vertex of the parabola that is given by the equation below?
We will be able to identify the answer if we have the equation. We can only check on the coordinates from the given vertex.
What is the y axis on a graph?
The y-values (the second number) in each coordinate (point) given to you. For example, the point (4,8) would have a y-value of 8

What is the name given to the point (00)?
The point (0,0) is called the origin in a Cartesian coordinate system. It serves as the reference point for defining the position of all other points in the plane. The x-coordinate and y-coordinate of the origin are both zero, making it the intersection of the x-axis and y-axis.
How do you determine y-intercept from 1 given coordinate?
It is impossible to figure it out with just one coordinate and no line. Maybe your line extends through the x and y system and you were given one coordinate. Take that coordinate and find the rise over run (slope). Follow that rise over run all the way to the y-axis. Whatever point you are on once you hit the y-axis that is the y-intercept.
