Question

1. what is the first step in applying the distance formula?

a. subtracting the coordinates
b. dividing the coordinates
c. adding the coordinates
d. multiplying the coordinates

Explanation:

Step1: Recall distance formula

The distance formula between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$.

Step2: Identify first operation

The first mathematical step in this formula is subtracting the corresponding $x$-coordinates and $y$-coordinates.

Answer:

a. Subtracting the coordinates
