Someone help me plz.

Question

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 4−x and y = 2−x+1 intersect are the solutions of the equation 4−x = 2−x+1. (4 points)

Part B: Make tables to find the solution to 4−x = 2−x+1. Take the integer values of x between −2 and 2. (4 points)

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

Answer 1

Part A)

 

That x value is where the two y values are the same.

 

 

Part B is self explanatory.

 

 

Part C)

 

Draw the two lines on the same coordinate grid.  Find the point of intersection.
