Answer:

y = - 8x + 20

Explanation:

the equation of a line in slope- intercept form is

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

y = - 8x - 5 ← is in slope- intercept form

with slope m = - 8

• Parallel lines have equal slopes , then

y = - 8x + c ← is the partial equation of the parallel line

to find c substitute (3, - 4 ) into the partial equation

- 4 = - 8(3) + c = - 24 + c ( add 24 to both sides )

20 = c

y = - 8x + 20 ← equation of parallel line
