Find the distance between the two coordinate points ex 1

The video tutorial explains how to find the distance between two coordinate points using the distance formula. It begins with an introduction to the concept and the formula, followed by a detailed explanation of the variables involved, such as X and Y coordinates with subscripts. The tutorial then demonstrates the application of the formula through a step-by-step calculation, ensuring to highlight common mistakes like handling negative signs. Finally, the video concludes with the calculation of the distance, emphasizing the importance of a positive result.

What is the main challenge when using certain values like sqrt 3 on a coordinate plane?

• They cannot be used in equations.

• They are not real numbers.

• They are always negative.

• They are difficult to plot accurately.

Why are subscripts used in the distance formula?

• To simplify the formula.

• To differentiate between the coordinates of two points.

• To indicate the order of operations.

• To make the formula more complex.

What is the correct format of the distance formula?

• X2 - X1 + Y2 - Y1

• X2 - X1 squared + Y2 - Y1 squared

• X2 + X1 squared + Y2 + Y1 squared

• X2 * X1 + Y2 * Y1

What happens when you subtract a negative number in the distance formula?

• It becomes zero.

• It turns into a positive number.

• It remains the same.

• It becomes a larger negative number.

What is the final result of the distance calculation in the example?

• 8

• 6

• 5

• 7
