To plot the given points on a grid:
i) Point A(2, 3):
Start by locating the point (2, 3) on the grid. Count 2 units to the right from the origin (0, 0) on the x-axis, and then 3 units up from there on the y-axis. Mark this point as A on the grid.
ii) Point B(1, -4):
Locate the point (1, -4) on the grid. Count 1 unit to the right from the origin on the x-axis and then 4 units down from there on the y-axis. Mark this point as B on the grid.
Point C has the same x-coordinate as B and the same y-coordinate as A.
To find the x-coordinate of B and the y-coordinate of A, you can look at their respective coordinates.
According to the given information, the x-coordinate of B is 1, and the y-coordinate of A is 3.
Plot the point (1, 3) on the grid. Count 1 unit to the right from the origin on the x-axis, and then 3 units up from there on the y-axis. Mark this point as C on the grid.
Point D has the same x-coordinate as the y-coordinate of B and the same y-coordinate as the x-coordinate of A.
To find the x-coordinate of the y-coordinate of B, you can simply look at the y-coordinate of B, which is -4.
To find the y-coordinate of the x-coordinate of A, you can look at the x-coordinate of A, which is 2.
Therefore, the x-coordinate of D is -4, and the y-coordinate of D is 2.
Plot the point (-4, 2) on the grid by counting 4 units to the left from the origin on the x-axis, and then 2 units up from there on the y-axis. Mark this point as D on the grid.
Now, you should have all the points A, B, C, and D plotted on the grid.
