Sarah played a game in which she could either lose or gain points each round. At the end of 5 rounds, she had 8 points. After one more round, she had points. Express the change in points in the most recent round as an integer .

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)
