Answer:
when two lines are parallel to each other(their slopes(m) are always equal)
y = mx+c
y =1/5(x+4)
y=1/5x+4/5
comparing the values
m =1/5
since it passes through point(3,8)
y-y1 = m(x-x1)
y-8=1/5(x-3)
multiply both sides by 5
5(y-8) =x-3
5y -40 = x-3
5y =x-3 +40
5y =x +37
divide both sides by 5
y = 1/5x +37/5
