Think about a chessboard, however as an alternative of squares, you’ve got bought factors with their x and y values.
When labeling factors on the coordinate grid, it is important to notice the x-value (the one on the x-axis) and the y-value (the one on the y-axis). Take, as an illustration, level A, which is 3 models to the proper of the origin and a pair of models up (the y-axis). You’d label it as (3, 2). The origin, the place to begin, is all the time (0, 0). When labeling the second level, keep in mind that you are searching for the subsequent set of coordinates on the grid that outline your line.
