lakkis [162]

Answer:

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
