Question 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?
Answer: 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 Log in to Reply
Answer:
The y coordinate is 6 and the x coordinate is 4
I hope this helps!
Answer: 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
