For each point given of the form (x,y), you move along the horizontal x-axis x number of points. Positive numbers move to the right from the origin. Negative numbers move to the left from the origin. Then, you move vertically, parallel to the y-axis to find the 2nd y-value. Positive values move up, while negative numbers move down. Draw your point at that point.
The first point you are given is (0,0). Starting from the origin (i.e., where the x-axis and y-axis meet), you are told to move a distance of x=0 along the x-axis, followed by a distance of y=0 parallel to the y-axis. Luckily a distance of zero isn't very far from the origin!
The second point you are given is (1,3). This time, you are told to move a distance of x=1 along the x-axis, followed by a distance of y=3 parallel to the y-axis.
The third point you are given is (-2,4). This time, you are told to move a distance of x=-2 left along the x-axis, followed by a distance of y=4 parallel to the y-axis.
