I am trying to help my sister can someone help me?

Find the midpoint of a line segment between the points (4,5) and (-14, -7) in the coordinate plane.

 

[happy]

The midpoint of a segment with endpoints (x1 , y1) and (x2 , y2) has coordinates

(x1+x2)/2, (y1+y2)/2

 

[thetomps]

so what do I do to solve happy (sorry I am so lost)

 

[happy]

use the formula I gave


(4,5)= (x1,y1)

(-14, -7)= (x2,y2)

 

[thetomps]

(-5, 1) ?

 

[stapel]

Check the sign on your y-coordinate.

Hello, thetomps!

Find the midpoint of a line segment between the points (4,5) and (-14, -7) in the coordinate plane.

The midpoint between (x₁,y₁) and x₂,y₂)

. . is located at: .x = (x₁ + x₂)/2, .y = (y₁ + y₂)/2

In baby-talk: "Average the x's, average the y's".


We have: .x .= .[4 + (-14)]/2 .= .-10/2 .= .-5

. . . . . . . . .y .= .[5 + (-7)]/2 .= .-2/2 = -1


Therefore, the midpoint is: .(-5,-1)
