Question

Midpoint of the line segment (-1,5) (-8,-4)

Answer 1

Answer:-4.5,0.5

Step-by-step explanation:midpoint =x1+x2/2, y1+y2/2

-1+-8/2=x,-4+5/2=y

-9/2=x,1/2=y

-4.5=x, 0.5=y

Answer 2

Answer:

(- $\frac{9}{2}$, $\frac{1}{2}$ )

Step-by-step explanation:

Using the midpoint formula

Given 2 points (x₁, y₁ ) and (x₂, y₂ ), then midpoint is

($\frac{x_{1}+x_{2} }{2}$, $\frac{y_{1}+y_{2} }{2}$)

with (x₁, y₁ ) = (- 1, 5) and (x₂, y₂ ) = (- 8, - 4), then midpoint

= ($\frac{-1-8}{2}$, $\frac{5-4}{2}$ )

= ( - $\frac{9}{2}$, $\frac{1}{2}$ )
