Answer:
y =
x - 5
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 )
y =
x + 4 ← is in slope- intercept form
with slope m = 
• Parallel lines have equal slopes , then
y =
x + c ← is the partial equation
to find c substitute (5, - 4 ) into the partial equation
- 4 = 1 + c ⇒ c = - 4 - 1 = - 5
y =
x - 5 ← equation of parallel line
Multiply the binomials:
(3x + 4)(5x - 2)

Final answer
Option B is the final answer
(1/3) + (1/2)
=> [(1×2)/(3×2)] + [(1×3)/(2×3)]
=> (2/6) + (3/6)
=> (5/6)
