Pre-Algebra Examples

(1, 1)

$(1, 1)$ ,

(3, 3)

$(3, 3)$

Step 1

Use the midpoint formula to find the midpoint of the line segment.

(\frac{x_{1} + x_{2}}{2}, \frac{y_{1} + y_{2}}{2})

$(\frac{x_{1} + x_{2}}{2}, \frac{y_{1} + y_{2}}{2})$

Step 2

Substitute in the values for

(x_{1}, y_{1})

$(x_{1}, y_{1})$ and

(x_{2}, y_{2})

$(x_{2}, y_{2})$ .

(\frac{1 + 3}{2}, \frac{1 + 3}{2})

$(\frac{1 + 3}{2}, \frac{1 + 3}{2})$

Step 3

Add

1

$1$ and

3

$3$ .

(\frac{4}{2}, \frac{1 + 3}{2})

$(\frac{4}{2}, \frac{1 + 3}{2})$

Step 4

Divide

4

$4$ by

2

$2$ .

(2, \frac{1 + 3}{2})

$(2, \frac{1 + 3}{2})$

Step 5

Add

1

$1$ and

3

$3$ .

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

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

Step 6

Divide

4

$4$ by

2

$2$ .
