Question

Y= 1/4x + 7 y = 1/2x + 5 The y-coordinate of the solution to the system shown is ____

9

11 1/2

19

Answer 1

y+9

Explanation:

Answer 2

1/4x + 7 = 1/2x + 5....u basically sub one y in for the other y
7 - 5 = 1/2x - 1/4x
2 = 2/4x - 1/4x
2 = 1/4x
2 / (1/4) = x
2 * 4/1 = x
8 = x

y = 1/4x + 7
y = 1/4(8) + 7
y = 2 + 7
y = 9 <====
