Answer:
Y=3/7x+8 and y=-7/3x-34/3(11 1/3)
Step-by-step explanation:
for the perpendicular line, the slope is the opposite inverse (3/7) and since 3/7×-7=-3, -3+8=5, hence, y=3/7x+8.
for the parallel line the slope is the same, and since -7/3×-7=49/3,
and 49/3-15/3(5)=34/3, the equation is y=-7/3-34/3
