Find the distance between (-4,2) and (10,2).

satela [25.4K]

Answer:

Step-by-step explanation:

1) To find the distance between two points you'll need to use the distance formula:

d= $\sqrt{(x1 - x2)^{2} + (y1 - y2)^{2} }$

2) Figure out which points you'll want to set:

(x1,y1) = (-4,2) (x2,y2) = (10,2)

3) Substitute your values into the formula:

$= \sqrt{(-4 - 10)^{2} + (2-2)^{2} }\\= \sqrt{(-14)^{2} + (0)^{2} }\\= \sqrt{196 }\\= 14$
