Respuesta :

-2x + 4y = 8
4y = 2x + 8
y = 1/2x + 2

m = 1/2

y + 1 = 1/2(x + 5)

y = 1/2x + 3/2

Answer:

y = 1/2 x + 3/2

Step-by-step explanation:

We need to start by finding the slope of the given line, since a line parallel to it will have the same slope. Then we need to solve for y in the given equation;

- 2 x + 4 y = 8

add 2x to both sides

4 y = 2 x + 8

divide both sides by 4 to isolate y

y = 1/2 x + 2

Then, the slope we are looking for is "1/2"

Now we write the equation of the parallel line we are trying to find, in "point slope form", using the point (-5, -1) we want to have on the line:

y = m (x - x1) + y1

replacing m with our slope 1/2, x1 with -5, and y1 with -1:

y = 1/2 (x - -5) + (-1)

y = 1/2 x + 5/2 - 1

y = 1/2 x + 3/2
