Question

Find the midpoint of CD. C= (7,-4) and D= (-8,-5)

Answer 1

Answer:

(-0.5 , -4.5)

Step-by-step explanation:

The formula for midpoint is (x1+x2)/2 , (y1+y2)/2

(7, -4) and (-8, -5) are our cordinate points, so we plug them in into our formula

(7+(-8))/2 = -0.5 (<-- our x-axis)

(-4+-5)/2 = -4.5 (<--- our y-axis)

Hope this helps!

Answer 2

Answer:

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

Step-by-step explanation:

The equation of a midpoint is as follows:

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

The x-coordinate:

x1 = 7, x2 = -8

7+(-8) = -1

Divide by 2 to get the x-midpoint

-1/2

The y-coordinate

y1 = -4, y2 = -5

-4 + (-5) = -9

Divide by 2 to get the y-midpoint

-9/2

You get:

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