Find the midpoint of X (26,56) and Y (26,1)

Svetradugi [14.3K]

Answer:

(26, $\frac{57}{2}$ )

Step-by-step explanation:

Hi there!

We are given the coordinates (26, 56) and (26, 1)

We want to find the midpoint of these two points

The midpoint can be found using the formula $(\frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2})$ , where $(x_1, y_1)$ & $(x_2, y_2)$ are points

We have 2 points, which is what we need to find the midpoint, but let's label the values of the points to avoid confusion and mistakes when actually calculating

$x_1=26\\y_1=56\\x_2=26\\y_2=1$

Now substitute these values into the formula.

$(\frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2})$

$(\frac{26 + 26}{2} , \frac{56+ 1}{2})$

Add the numbers together

$(\frac{52}{2} , \frac{57}{2})$

Divide

(26, $\frac{57}{2}$ )

Hope this helps!
