Example Question #51 : Lines
A line segment on the coordinate plane has an endpoint at ; its midpoint is at .
True or false: Its other endpoint is located at .
True
False
True
The midpoint of a line segment with endpoints and is located at .
Therefore, set
and
In the first equation, set and solve for :
Multiply both sides by 2:
Subtract 3.8 from both sides:
In the second equation, set and solve for :
Multiply both sides by 2:
Add 1.7 to both sides:
The other endpoint is indeed at , so the statement is true.
Example Question #1 : Distance Formula
A line segment begins from the origin and is 10 units long, which of the following points could NOT be an endpoint for the line segment?
By the distance formula, the sum of the squares of each point must add up to 10 squared. The only point that doesn't fufill this requirement is (5,9)
Example Question #1 : Distance Formula
A line segment is drawn starting from the origin and terminating at the point . What is the length of the line segment?
Using the distance formula,
Example Question #3 : Distance Formula
What is the distance between and ?
In general, the distance formula is given by: and is based on the Pythagorean Theorem.
Let and
So the equation to soolve becomes or
Example Question #3 : Distance Formula
If we graph the equation what is the distance from the y-intercept to the x-intercept?
First, you must figure out where the x and y intercepts lie. To do this we begin by plugging in to our equation, giving us . Thus . So our x-intercept is the point . We then plug in , giving us , so we know our y-intercept is the point . We then use the distance formula and plug in our points, giving us

Find the distance of the line connecting the pair of points
and .
By the distance formula
where and
we have
