Question

What is the distance between the points (-1, 8) and (4.8) in the coordinate plane?

Answer 1

To find the distance between any points:

⇒ we must know the distance formula

⇒ Distance Formula:
`\sqrt{(x_(2)-x_(1))^2+(y_(2)-y_(1))^2 } }`

• 
  `(x_(1) ,y_(1) )` --> (-1,8)
• 
  `(x_(2) ,y_(2) )` --> (4,8)

Let's Solve:

Distance Formula =
`√((4--1)^2+(8-8)^2) =√(5^2) =√(25)` = 5

Thus the distance between the points is 5

Hope that helps!
