Question

Find the distance between the points (-4, 10) and (-4, -8).

Answer 1

Answer:

18 units

Step-by-step explanation:

(-4 , 10) and (-4, -8)

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

              $= \sqrt{(-4-[-4])^{2}+(-8-10)^{2}}\\\\= \sqrt{(-4+4)^{2}+(-18)^{2}}\\\\=\sqrt{0 + 324}\\\\=\sqrt{324}\\\\= 18$
