Formula for coordinates of midpoint,

x= (x1+x2)/2
y=(y1+y2)/2,

where (x1,y1), (x2,y2) coordinates of the end-points.

-1=(x1-8)/2
-2=x1-8
x1=-2+8
x1=6

1=(y1+4)/2
2=y1+4
y1=2-4
y1= - 2

K(6,-2)

simplify ---

5x=20

Divide both sides by 5 -----

5x/5 = 20/5

Simple....

$\frac{3}{4} x\ \textless \ \frac{9}{2}$

x<6

This means that on your graph at 6 it's a circle (not colored in) and it goes to the left indefinitely...

Thus, your answer.

Please include work!

aleksandrvk [35]

Answer:

A) y = x^2 -1

B) -y = 2x^2 +1 We multiply B) by -1

B) y = -2x^2 -1

We can then say x^2 -1 = -2x^2 -1

3 x^2 = 0

x = 0

************* Double-Check: ******************

Equation A) y = -1 and

Equation B) y = -1
