Question

Find the distance of a line given the following points. R(3, 1), W(-1, -2)

Answer 1

`√(13)`

Explanation:

we can solve this using the distance formula:
`\sqrt{(x_(2)-x_1)^(2) + (y_(2)-y_1)^(2)}`

`x_1, y_1` is (3, 1)

`x_2, y_2` is (-1, -2)

`√((1-3)^2 + (-2-1)^2)`

which simplifies to:
`√((-2)^2 + (-3)^2)`

then:
`√(2^2 + 3^2)` or:
`√(4+9)`

your final answer is:
`√(13)` or about 3.61
