Answer:
15 units
Step-by-step explanation:
The formula for distance is
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Given
(12,-7) and (-3,-7)
x₁=12, x₂=-3 , y₁=-7 , y₂=-7
Applying formula
[tex]d=\sqrt{(-3-12)^2+(-7--7)^2} \\\\\\d=\sqrt{(-15^2)+0} \\\\\\d=\sqrt{225} \\\\\\d=15[/tex]
Answer:
Your answer would be 15 units.
