Question

The class of math is mapped on a coordinate grid with the origin being at the center point of the hall. Mary’s seat is located at the point (9, -8) and Betty’s seat is located at (5, -10). How far is it from Mary’s seat to Betty’s seat?

SOMONE PLS HELP ME WITH THIS

Answer 1

to find the distance b/t 2 points you need to use the distance formula. that is

distance = square root of (x2-x1)^2 + (y2-y1)^2


to fill it in, it is

(it doesnt matter which point you start with, as long as its consistent)

x1 = 9
x2 = 5
y1 = -8
y2 = -10

square root of (5-9)^2 + (-10-8)^2

lets do algebra!

square root of (-4)^2 + (-18)^2

square root of 16 + 324

square root of 340


Distance = 18.4391 units.

I hope this helps!
