Question

What is the difference from c(2,-1) to d(5,3) a.5 units b.25 units c. 1 unit d.

Answer 1

Answer: A) 5 units

====================================================

Explanation:

The two points given are

C = (x1,y1) = (2,-1)

D = (x2,y2) = (5,3)

Use the distance formula

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(2-5)^2 + (-1-3)^2}\\\\d = \sqrt{(-3)^2 + (-4)^2}\\\\d = \sqrt{9 + 16}\\\\d = \sqrt{25}\\\\d = 5$

The distance from C to D is 5 units. This is the same as saying segment CD is 5 units long.
