Answer:

x + y = 5

Explanation:

The equation of a line in slope- intercept form is

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

Given

x + y = 4 ( subtract x from both sides )

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

with slope m = - 1

Parallel lines have equal slopes , then

y = - x + c ← is the partial equation

To find c substitute (3, 2 ) into the partial equation

2 = - 3 + c ⇒ c = 2 + 3 = 5

y = - x + 5 ( add x to both sides )

x + y = 5 ← equation of parallel line
