Hello from MrBillDoesMath!
Answer:
a. 2
b. - (1/2)
Discussion:
a. The slope of the line y = 2x +3 is 2. A line parallel to this lien has the same slope, that is, 2.
b. Two lines are perpendicular if the products of their slopes is -1. Sine the slope of the original line is 2 the slope. "m", of the perpendicular line is given by
2*m = -1
or
m = -1/2
Thank you,

1/40,000 = h/10
40,000h = 10
h = 10/40,000
h = 1/4,000
