Y = -2 x - 9
3 x - 4(-2 x - 9 ) = -8
3 x + 8 x + 36 = - 8
11 x = - 44,   x = - 4 
y = 8 - 9 ,      y = -1
This is a unique solution, the system is independent.

What is the other endpoint if one endpoint is (10,12) and the midpoint is (6,9).?
Lubov Fominskaja [6]

Answer:

(2,\, 6).

Step-by-step explanation:

Let (x_{0},\, y_{0}) and (x_{1},\, y_{1}) denote the two endpoints.

The formula for the midpoint of these two points would be:

\displaystyle \left(\frac{x_{0} + x_{1}}{2},\, \frac{y_{0} + y_{1}}{2}\right).

(Similar to taking the average of each coordinate.)

In this question, it is given that x_{0} = 10 whereas y_{0} = 12. Substitute these two values into the expression for the coordinate of the midpoint:

  • x-coordinate of the midpoint: \displaystyle \frac{10 + x_{1}}{2} = 6.
  • y-coordinate of the midpoint: \displaystyle \frac{12 + y_{1}}{2} = 9.

Solve these two equations for x_{1} and y_{1}: x_{1} = 2 whereas y_{1} = 6.

Hence, the coordinate of the other point would be (2,\, 6).
