Asked by Annabelle

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 2−x and y = 4x + 3 intersect are the solutions of the equation 2−x = 4x + 3.

Part B: Make tables to find the solution to 2−x = 4x + 3. Take the integer values of x only between −3 and 3.

Part C: How can you solve the equation 2−x = 4x + 3 graphically?

There seems to be a lot of people needing help in Algebra 1.
Answered by Steve
clearly, y=y
now substitute in the two different definitions.

Draw the two lines. The solution is where they intersect.

Your explanation is not very well done. Thank you for your time though :)
