Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 4−x and y = 8−x−1 intersect are the solutions of the equation 4−x = 8−

Question

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 4−x and y = 8−x−1 intersect are the solutions of the equation 4−x = 8−x−1. (4 points)

Part B: Make tables to find the solution to 4−x = 8−x−1. Take the integer values of x between −3 and 3. (4 points)

Part C: How can you solve the equation 4−x = 8−x−1 graphically? (2 points)

Answer 1

I made a comment but it didn't get posted.

Check your work. You have a typo.

4-x=8-x-1

4-x=7-x

add x to both sides

4≠7
