What is the length of MN?

(please help!!!)

√52

Step-by-step explanation:

For this question, you need to use the distance formula:

d= √[(x2 - x1)^2 + (y2-y1)^2]

The coordinates for point M are (5,2) and the coordinates for point N are (-1,-2). Let (x1, y1) be point M, and (x2,y2) be point N.

Now, you simply need to plug in the coordinates and solve for d.

d=√ [(-1 - 5)^2 + (-2 - 2)^2]

d= √ [(-6)^2 + (-4)^2]

d= √(36 + 16)

d= √52

b) well because you get well
