HiSET: Math : Midpoint of line segments

Example Questions

Example Question #1 : Midpoint Of Line Segments

Give the coordinates of the midpoint of the line segment whose endpoints are the intercepts of the line of the equation

.

None of the other choices gives the correct response.

Explanation:

The x-intercept and y-intercept of the line of an equation can be found by substituting 0 for and , respectively, as follows:

x-intercept:

Substitute and simplify:

Solve for by dividing by 2 on both sides:

The x-intercept of the line is located at

The y-intercept can be found by setting and solving for in a similar fashion:

The y-intercept is located at .

The midpoint of a line segment, given its endpoints and , is located at

;

substituting accordingly,

The midpoint is located at .

Example Question #2 : Midpoint Of Line Segments

What is the midpoint of the line segment created by the points  and ?

Explanation:

The midpoint of the line segment between two points

and

is given by the formula

.

Thus, since the line segment is generated by

and

applying the midpoint formula we have

as the midpoint.
