Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 4-x and y = 2x + 3 intersect are the solutions of the equation 4-x = 2x + 3. (4 points)
Part B: Make tables to find the solution to 4-x = 2x + 3. Take the integer values of x between −3 and 3. (4 points)
Part C: How can you solve the equation 4-x = 2x + 3 graphically? (2 points)
