What is the distance between the points (5,1) and (-3,-5)?<br>​
Charra [1.4K]

Answer

\boxed{10 \: \:  units}

Step by step explanation

Let the points be A and B

A ( 5 , 1 ) ⇒ ( x₁ , y₁ )

B ( -3 , -5 )⇒ ( x₂ , y₂ )

Now, let's find the distance between theses two points:

Distance = \mathsf{ \sqrt{ {(x2 - x1)}^{2} +  {(y2 - y1)}^{2}  } }

Plug the values

\mathsf{ \sqrt{ {( - 3 - 5)}^{2} +  {( - 5 - 1)}^{2}  } }

Calculate

\mathsf{ \sqrt{ { ( - 8)}^{2}  +  {( - 6)}^{2} } }

Evaluate the power

\mathsf{ \sqrt{64 + 36} }

Add the numbers

\mathsf{ \sqrt{100} }

Write the number in exponential form with a base of 10

\mathsf  {\sqrt{ {10}^{2} } }

Reduce the index of the radical and exponent with 2

\mathsf{10 \: units}

-------------------------------------------------------------------------------

The distance formula is used to determine the distance ( d ) between two points. If the co-ordinates of the two points are ( x₁ , y₁) and ( x₂ , y₂ ) , the distance equals the square root of x₂ - x₁ squared + y₂ - y₁ squared.

Hope I helped!

Best regards!
