    Use the distance formula., if you know it!

    \[distance = {\sqrt(x_2 - x_1)^2 + (y_2 - y_1)^2}\]

    \[d = \sqrt(x^2 - x^1)^2 + (y^2 - y^1)^2\]

    Yeah, but 2 and 1 are subs... not exponents!

    \[d = \sqrt(3 - 1)^2 + (-4 + 6)^2?\]

    \[= \sqrt(2)^2 + (10)^2\]

    \[\sqrt(4 + 100) = \sqrt(104) \approx \]

    And rounded to the nearest tenth is approximately 10.2? Thanks @ParthKohli ! :)

    Actually you can express it in radical form, since that's more accurate!

    \[\sqrt{104 } \implies \sqrt{2 \times 2 \times 2 \times 13} \implies 2\sqrt{26}\]
