Distance Formula D=√(x2-x1)² + (y2 - y₁) ² a. 8.149 b. 8.84 c. 9.438 d.12.369 ​
lakkis [162]

Answer:

d

Step-by-step explanation:

using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (- 2, 4 ) and (x₂, y₂ ) = (10, 1 )

d = \sqrt{10-(-2))^2+(1-4)^2}

   = \sqrt{(10+2)^2+(-3)^2}

  = \sqrt{12^2+9}

  = \sqrt{144+9}

  = \sqrt{153}

  ≈ 12.369
