Example Question #434 : Problem Solving
Which of the following points is on the -axis?
A point is located on the -axis if and only if it has a -coordinate equal to zero. So the answer is .
Example Question #282 : Geometry
A line segment on the coordinate plane has its endpoints at the points with coordinates and . Give the midpoint of the segment.
The -coordinate of the midpoint can be found by dividing the sum of the -coordinates of the endpoints by 2:
The -coordinate of the midpoints is found similarly:
Example Question #1 : Coordinate Geometry
A line segment on the coordinate plane has its endpoints at the points with coordinates and . Give the coordinates of the midpoint of the segment.
The -coordinate of the midpoint can be found by dividing the sum of the -coordinates of the endpoints by 2:
The -coordinate of the midpoint is found similarly:
.
The correct response is .
Example Question #284 : Geometry
A line segment on the coordinate plane has its endpoints at the points with coordinates and . Give the coordinates of the midpoint of the segment.
The -coordinate of the midpoint is half the sum of the -coordinates of the endpoints:
The -coordinate of the midpoint is found similarly:
The correct response is .
Example Question #281 : Geometry
Angela plotted points A through E on the coordinate plane shown below.
Which point is located at the ordered pair
Point D
Point C
Point A
Point B
Point E
Point B
Start at point (0, 0) in the bottom, left corner of the the coordinate plane. From there, count right 2 spaces. This is the first number in the given ordered pair. From that point, count up 8 spaces. This is the second number in the given ordered pair.
By moving right 2 and up 8, you should have found Point B.
Example Question #2 : Coordinate Geometry

Find the slope of the line that passes through coordinates and .
The formula for slope is:
In this particular question our values are given as follows.
Substituting the above values into the formula for slope we get,
.
Example Question #436 : Problem Solving
Billy set up a ramp for his toy cars. He did this by taking a wooden plank and putting one end on top of a brick that was 3 inches high. He then put the other end on top of a box that was 9 inches high. The bricks were 18 inches apart. What is the slope of the plank?
The value of the slope (m) is rise over run, and can be calculated with the formula below:
The coordinates of the first end of the plank would be (0,3), given that this is the starting point of the plank (so x would be 0), and y would be 3 since the brick is 3 inches tall.
The coordinates of the second end of the plank would be (18,9) since the plank is 18 inches long (so x would be 18) and y would be 9 since the box was 9 inches tall at the other end.
From this information we know that we can assign the following coordinates for the equation:
and
Below is the solution we would get from plugging this information into the equation for slope:
This reduces to
