Question

Find the distance between the two points rounding to the nearest tenth (if necessary).

(-4,2) and (2, -6)
Answer: _____

Answer 1

d = 10

Explanation:

`d=√((x_2-x_1)^2+(y_2-y_1)^2)\\\\(-4,2)\quad\implies\quad x_1=-4\,,\ y_1=2\\\\(2,-6)\quad\implies\quad x_2=2\,,\ y_2=-6\\\\d=√((2+4)^2+(-6-2)^2)= √(6^2+(-8)^2)= √(26+64)= √(100)=10`
