What is a y coordinate?
A y coordinate is when you have a long line (y axis) and you coordinate (put numbers on that line) and you graph them
What do all the points on the y axis have in common?
If the y axis is part of the Cartesian coordinate system, then the other coordinate is zero.Their x-axis value is 0.
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 describes the location of any point on a coordinate grid?
its called an ordered pair. it is an x-coordinate and a y-coordinate (x,y)
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.
