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

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

m = 1/2

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

y = 1/2x + 3/2

(2x+1)/2=(x+2)/5<br><br>if possible can you show me step by step how to get the answer <br>​
katrin2010 [14]

Answer:

\boxed{\bold{Decimal \ Form: \ x \ = \ -0.125}}

\boxed{\bold{Fraction \ Form:x=-\frac{1}{8}}}

Step By Step Explanation:

Apply Fraction Cross Multiply: If \bold{\frac{a}{b}=\frac{c}{d}:then\ a\cdot \:d=b\cdot \:c}

\bold{\left(2x+1\right)\cdot \:5=2\left(x+2\right)}

\bold{\left(2x+1\right)\cdot \:5: \ 10x+5}

\bold{2\left(x+2\right): \ 2x+4}

\bold{10x+5=2x+4}

Subtract 4 From Both Sides

\bold{10x+5-5=2x+4-5}

Simplify

\bold{10x=2x-1}

Subtract 2x From Both Sides

\bold{10x-2x=2x-1-2x}

Simplify

\bold{8x=-1}

Divide Both Sides By 8

\bold{\frac{8x}{8}=\frac{-1}{8}}

Simplify

\bold{x=-\frac{1}{8}}

Turn Fraction Into Decimal

\bold{-1 \ \div \ 8 \ = \ -0.125}

\bold{-0.125}
