Answer:

2x + y = 4

Explanation:

the equation of a line in slope- intercept form is

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

given equation of line

2x + y = 6 ( subtract 2x from both sides )

y = - 2x + 6 ← in slope- intercept form

with slope m = - 2

Parallel lines have equal slopes , then

y = - 2 x + c ← is the partial equation

to find c, substitute (4, - 4 ) for x and y into the partial equation

- 4 = - 2(4) + c = - 8 + c ( add 8 to both sides )

4 = c

y = - 2x + 4 ← equation in slope- intercept form

add 2x to both sides

2x + y = 4 ← equation in standard form
