Exercise 10 Page 617

Start by plotting the endpoints G and H.

Practice makes perfect

To graph the line segment, we first need to plot the endpoints. In an ( x, y) ordered pair, the first number shows the x-coordinate and the second number shows the y-coordinate.

x-coordinates

To plot G( 3, - 4) and H( 3, 4) we first find 3 on the x-axis and make a mental note of this grid line. The x-coordinate 3 tells us to move three units in the positive horizontal direction.

y-coordinates

Next, we find - 4 on the y-axis and follow this grid line until it collides with the grid line from our x-coordinates. The y-coordinate - 4 tells us to move four units in the negative vertical direction. After that, we find 4 and follow this grid line. The y-coordinate 4 tells us to move four units in the positive vertical direction.

The points G( 3, - 4) and H( 3, 4) lay on the points at which the grid lines intersect.

Line Segment

Finally, to graph the line segment we will connect the two points with a straight line.
