Tyler's house, and Tyler left his house at the same time, walking toward Jenna's house. we both walked along the same road and met after a water. The graph below shows the distances, f(x), from Jenna's house, in miles, after x hours of walking.
Which system of equations represents the graph lines?
f(x) = ½x + 4
g(x) = -¾x - 1
f(x) = ½x - 4
g(x) = -¾x + 1
f(x) = 2x + 4
g(x) = -¾x - 1
f(x) = 2x + 4
g(x) = -¾x + 1

Angie and Evan spent the day at the Conroe Christmas, enjoying their favorite activities: Snow Hill and the carousel. Their tickets were stamped each time they rode. Angie rode the carousel twice while Evan rode three times. Evan also rode Snow Hill six times while Angie rode three times. By the end of the day, their total spending was recorded on their tickets as seen in the image.
Let x represent the cost of riding Snow Hill and y represent the cost of riding the carousel, which system of equations represents the situation?
3x + 2y = 39
6x + 3y = 21
2x + 3y = 21
3x + 6y = 39
3x + 2y = 21
6x + 3y = 39
3x - 2y = 21
6x - 3y = 39
