Question

Sadie models her

neighborhood on a coordinate plane so that
her school is at (8, 12) and a store is at (14, 3).
What are the coordinates of the point halfway
between the school and the store?

Answer 1

Answer: (11, 7.5) or (11, 15/2)

Explanation:

Slope:

`(12-3)/(8-14) =(9)/(-6) =\boxed{-(3)/(2) }`

to find halfway between the vertical distance do

`(12-3)/2=9/2=4.5 + 3 = 7.5`

To find the horizontal distance do

`(14-8)/2 + 8=6/2 + 8 = 3 + 8 = 11`

`\boxed{\therefore\ \ \ the\ coordinates\ are\ (11,(15)/(2) ).}`

Answer 2

Answer: (11, 7.5)

Explanation:

((8, 12)+(14, 3))/2=

(8+14, 12+3)/2=

(22/2, 15/2)=(11, 7.5)
