Answer:
Step-by-stepapex answer to the left of 9.9 and to the right of 9.3 explanation:
To prove two equations have infinite solutions, you have to prove that those two equations are the same equations, but in a different form.
For example: Prove the equations are infinite
5y=2x+7
10y=4x+14
If you multiply the first equation by 2, and substitiute any of the numbers, you will get 0=0
Answer:
The answer to your question is (-1, -1)
Step-by-step explanation:
Data
A (1, -6)
B (-3, 4)
Formula
Xm =
Ym =
Process
1.- Substitute the values in the formula
x1 = 1 x2 = -3
Xm =
y1 = -6 y2 = 4
Ym =
2.- The midpoint is (-1, -1)
