Answer 1

Answer: y=x/2 + 3/2

Step-by-step explanation:

Answer 2

Answer:

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange - 2x + 4y = 8 into this form by adding 2x to both sides

4y = 2x + 8 ( divide all terms by 4 )

y = $\frac{1}{2}$ x + 2 ← in slope- intercept form

with slope m = $\frac{1}{2}$

Parallel lines have equal slopes, thus

y = $\frac{1}{2}$ x + c ← is the partial equation

To find c substitute (- 5, - 1) into the partial equation

- 1 = - $\frac{5}{2}$ + c ⇒ c = - 1 + $\frac{5}{2}$ = $\frac{3}{2}$

y = $\frac{1}{2}$ x + $\frac{3}{2}$ ← equation of parallel line
