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

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

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

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
