Answer:

y = 4x + 16

Explanation:

The equation of a line in slope- intercept form is

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

y = 4x + 5 ← is in this form

with slope m = 4

Parallel lines have equal slopes, thus

y = 4x + c ← is the partial equation

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

4 = - 12 + c ⇒ c = 4 + 12 = 16

y = 4x + 16 ← equation of parallel line
