The point in the middle of a line segment is called the _____________.

Which of the following would you use to determine the midpoint between two points on a graph?

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

• $y=mx+b$

• $a^2+b^2=c^2$

• $d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

Which of the following would you use to determine the distance between two points on a graph? Select ALL that apply.

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

• $y=mx+b$

• $a^2+b^2=c^2$

• $d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

•  $AB\ +\ BC\ =\ AC$  

What is the midpoint of the line segment shown?

Remember to write your answer as a point. Do NOT use spaces between characters. Write your answer as a decimal. Just write the answer...no need for a complete sentence.

What is the length of the line segment shown?

Write your answer as a decimal, rounded to the nearest hundredth. Just write the answer...no need for a complete sentence.
