    heres the question 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. (4 points) Part B: Make tables to find the solution to 2-x = 4x + 3. Take the integer values of x only between -3 and 3. (4 points) Part C: How can you solve the equation 2-x = 4x + 3 graphically? (2 points)

    both 2-x and 4x - 3 are equal to y therefore 2 - x = 4x - 3 (by The Transitive Property of Equality.)

    Oh thats not all the answer. The point of intersection is the solution because at that point the values of x and y satisfy both equations

    table will look like |dw:1438980401594:dw|

    you find the values by substituting the number for x in the expression for example for x = -2 it is 2 - x = 2-(-2) = 2+2 = 4 for x = -2 it is 4x - 3 = 4(-2) - 3 = -8 - 3 = -11

    so you can continue to compute values for x = 1,2 and 3

    for Part C you can plot points on graph paper form x = -3 and x = 3 using the values form the table where the 2 lines cut is the solution

    Thank you sooo much, I researched how to do this and found nothing. Your a lifesaver. I will give you a medal if you tell me how to.
