Multiple Choice

The distance formula is another way to write which of the following?

• Midpoint Formula

• Quadratic Formula

• Pythagorean Theorem

• Segment Addition Postulate

Multiple Choice

How is the distance formula correctly written?

• $$d=(x_2−x_1)^2+(y_2​−y_1​)^2​$$  

• $$d=\sqrt[]{(y_2−y_1)^2−(x_2​−x_1​)^2​}$$  

• $$d=\sqrt[]{(x_2−x_1)^2−(y_2​−y_1​)^2​}$$  

• $$d=\sqrt[]{(x_2−x_1)^2+(y_2​−y_1​)^2​}$$
