Which of the following is the y coordinate of the solution of the system of equations y = - 1/2 x+8 and y=x+ 2?

The whole solution is (4,6)  so the  y coordinate of the solution is 6.

Step-by-step explanation:

y = -1/2x + 8     and y= x +2

Using both equations substitute one of the equation into another an solve for x.

-1/2x + 8  = x + 2

         -8          -8

-1/2x = x  -6

-x          -x  

-1.5x = -6

 x =  4

Since the value of x is 4 input in into the equation and solve for y.

y = -1/2(4) + 8

y = -2 + 8

y = 6

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
