Question

If a line has a midpoint at , and the endpoints are and , what is the value of ?

Tap to reveal answer

Answer

The midpoint of a line segment is halfway between the two $\small x$ values and halfway between the two $\small y$ values.

Mathematically, that would be the average of the coordinates: $(\frac{x_2+x_1}{2},\frac{y_2+y_1}{2})$ .

Plug in the values from the given points.

$(\frac{4+0}{2},\frac{y+0}{2})=(2,5)$

Now we can solve for the missing value.

$(\frac{4}{2},\frac{y}{2})=(2,5)$

$\frac{4}{2}=2$

The $\small x$ values reduce, so both $\small x$ values equal $\small 2$ . Now we need to create a new equation to solve for the $\small y$ value.

$\frac{y}{2}=5$

Multiply both sides by to solve.

$(2)\frac{y}{2}=5(2)$

Answer

The midpoint of a line segment is halfway between the two $\small x$ values and halfway between the two $\small y$ values.

Mathematically, that would be the average of each coordinate: $(\frac{x_2+x_1}{2},\frac{y_2+y_1}{2})$ .

Plug in the values from the given points and solve.

$(\frac{5+0}{2},\frac{7+1}{2})$

$(\frac{5}{2},\frac{8}{2})$

We can simplify the fraction to give our final answer.

$(\frac{5}{2},4)$

Question

What is the midpoint of the line segment which connects and ?

Tap to reveal answer

Answer

To find the midpoint of a line segment, we find the average of the x and y coordinates of the endpoints. The average of two numbers is the sum of those numbers divided by . Thus, to find the x-coordinate of our midpoint, we find the average of and , and we get .

To find the y-coordinate of our midpoint, we find the average of and , which is .

Thus, our midpoint is
