Calculating Distance and Midpoint Between Points

What are the two main concepts discussed in this tutorial?

• Finding the slope and intercept of a line

• Finding the distance and midpoint between two points

• Finding the area and perimeter of a shape

• Finding the volume and surface area of a solid

What is the first step in using the distance formula?

• Assigning values to X1, Y1, X2, and Y2

• Calculating the midpoint

• Finding the slope

• Drawing a graph

What is the distance formula?

• X1 - X2 + Y1 - Y2

• X1 + X2 / 2 and Y1 + Y2 / 2

• Square root of (X2 - X1)^2 + (Y2 - Y1)^2

• X2 - X1 + Y2 - Y1

What is the final distance between the points (-2, 3) and (3, -9)?

• 13 units

• 10 units

• 15 units

• 12 units

What is the midpoint formula?

• X2 - X1 + Y2 - Y1

• X1 - X2 + Y1 - Y2

• X1 + X2 / 2 and Y1 + Y2 / 2

• Square root of (X2 - X1)^2 + (Y2 - Y1)^2

What is the x-coordinate of the midpoint between (-2, 3) and (3, -9)?

• 1
