Question

1. which formula is used to calculate the distance between two points on a coordinate plane?

a. pythagorean theorem
b. midpoint formula
c. distance formula
d. slope formula

Explanation:

The distance formula $d = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}$ is specifically used to find the distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ on a coordinate - plane. The Pythagorean theorem is related conceptually as the distance formula is derived from it. The mid - point formula finds the mid - point between two points, and the slope formula finds the slope of the line passing through two points.

Answer:

c. Distance formula
