Question

find the distance between points p(-2,-6) and
Q (-4,-2)​

Answer 1

Answer:

You will two two answers $\sqrt{20}$ or $\sqrt{12}$

Simplifying will give $2\sqrt{5}$ or $2\sqrt{3}$ respectively..

Step-by-step explanation:

As per Distance Formula PQ = $\sqrt{(x_{2}-x_{1})^{2} + (y_{2} -y_{1})^{2} }$

so X1 = -2    Y1 = -6

    X2= -4    Y1 = -2

Which Implies:-

PQ=$\sqrt{(-4+2)^{2}+(-2+6)^{2} }$

PQ = $\sqrt{-2^{2} + 4^{2} }$

PQ = $\sqrt{4+16}}$ or $\sqrt{-4+16}$

PQ = $\sqrt{20}$ or $\sqrt{12}$
