what is a x-coordinate and a y-coordinate?

Answer 1

when u see a graph, the two lines that are perpendicular to each other. the y axis is the one going up and the x axis is the one going sideways

Answer 2

They are coordinates used to mark a position of a point on a 2d graph in relation to the x and y axis. X is the horzantal axis, y is the vertical one. A coordinate is writen like so: (3,5). Coordinates are read like this: (X,Y). The x value tells you how far the point is above the X axis (or how far below, is the X value is negative). The Y value tells you how far the point is to the right of the Y axis (or to the left, if the Y value is negative) The point where the x axis and y axis intersect is (0,0).

Answer 3

Coordinates locate a point. the x coordinate tells you how far the point is left (negative) or right (positive) from the origin. the y coordinate tells you how far up (+) or down (-) the point is from the origin. so if the coordinates of the point are (3,2), it is 3 units right and 2 units up from the origin. (-4,-3) is 4 units left and 3 units down.
