Question

What is distance between 12,-7 and -3,-7

Answer 1

Answer:

15 units

Step-by-step explanation:

The formula for distance is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Given

(12,-7) and (-3,-7)

x₁=12, x₂=-3 , y₁=-7 , y₂=-7

Applying formula

$d=\sqrt{(-3-12)^2+(-7--7)^2} \\\\\\d=\sqrt{(-15^2)+0} \\\\\\d=\sqrt{225} \\\\\\d=15$
