Question

Find a distance between each pair point. When you answered to the nearest 10th (-2,-3) and (-4,4)

Answer 1

Use the formula:


`A(x_A;\ y_A);\ B(x_B;\ y_B)\\\\|AB|=√((x_B-x_A)^2+(y_B-y_A)^2)`

We have:


`A(-2;\ -3);\ B(-4;\ 4)`

substitute:


`|AB|=√((-4-(-2))^2+(4-(-3))^2)=√((-2)^2+7^2)\\\\=√(4+49)=√(53)\approx7.3`
