Im spending all my points for this smh

Figure abcd is a parallelogram. if point c lies on the line x = 2, what is the y-value of point c

(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)

Find the dimensions of the circle. area = 64π in.² r= in.
