Math Standards related to Graphing 2.0 Students use two-dimensional coordinate grids to represent points and graph lines and simple figures:
2.1 Draw the points corresponding to linear relationships on graph paper (e.g., draw 10 points on the graph of the equation y = 3 x and connect them by using a straight line).2.2 Understand that the length of a horizontal line segment equals the difference of the x- coordinates.2.3 Understand that the length of a vertical line segment equals the difference of the y- coordinates.
The basics of graphing :
The basics of graphing x y y = 3 + x An equation with 2 variables, usually named x and y. A function table Point of origin, where x=0 and y=0 A graph, also called a coordinate grid 0 3

-1 2 In some graphing problems, you won’t have an equation. Instead, you will be given a list of ordered pairs to plot on the graph, so you won’t need to make the function table. (0,3), (1,4), (-1,2) Ordered pairs: each pair of x and y points make the equation true. Coordinate points

More details about graphing X axis Y axis (0,3), (-1, -1), (2, -4) (2, -4) (0,3) (-1, -1) If x is positive and y is positive, the coordinate point will be in here. If x is positive and y is negative, the coordinate point will be in here. If x is negative and y is negative, the coordinate point will be in here. If x is negative and y is positive, the coordinate point will be in here. Some examples: In the 4th grade, most of your coordinate points will be located in the blue areas. However, you should know how to locate points in the yellow areas, too.

2.2 Understand that the length of a horizontal line segment equals the difference of the x- coordinates.2.3 Understand that the length of a vertical line segment equals the difference of the y- coordinates. :
2.2 Understand that the length of a horizontal line segment equals the difference of the x- coordinates.2.3 Understand that the length of a vertical line segment equals the difference of the y- coordinates. 2.2 means that the length of the purple line segment can be calculated by subtracting the two x coordinates. 6-3=3 The purple line segment is 3 units long.
2.3 means that the length of the purple line segment can be calculated by subtracting the two y coordinates. 5-1=4 The purple line segment is 4 units long.
