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 is y-coordinate in rectangular coordinate system?
A point's y coordinate is its vertical position, or how high or low it is.
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.
When a point lies on an x axis what do you know about its y coordinate?
Its y coordinate will be at zero.
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.

You can find the rise by the y-coordinate of the left point from the y-coordinate of the right point?

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 coordinate of the y-intercept of the line given the equation y equals 5x plus 21?
The y-intercept of that line is the point (0, 21).
What do you know about the y- coordinate of a point that lies on the x-axis?
If a point lies on the x-axis, then you know that the y-coordinate is zero.
What quadrant is a point that has a negative x coordinate and a negative y coordinate is located in?
The quadrant where a point has a negative x coordinate and a negative y coordinate is located in quadrant 3.
