Question

What is the y-intercept for the equation 2y + 4x = 8? a) -2 b) 4 c)2 d) -4

Answer 1

Answer:

The answer to your question is the letter B.

Step-by-step explanation:

Data

       2y + 4x = 8

Process

To find the y-intercept, just solve the equation of y.

1.- Subtract 4x in both sides of the equation

                     2y + 4x - 4x = -4x + 8

2.- Simplify

                           2y = -4x + 8

3.- Divide both sides by 2

                          2y/2 = (-4x + 8)/2

4.- Simplify

                              y = -2x + 4

5.- Find the y-intercept

The y-intercept is the number that has no variable on the right side of the equation.

In this example is 4
