**Damon**, Wednesday, December 28, 2011 at 5:29pm4 y = 3 x + 0

y = (3/4) x

slope = m = 3/4

y = x^3 + k

dy/dx = slope = 3 x^2

so

3 x^2 = 3/4

x^2 = 1/4

x = 1/2 (-1/2 is not in first quadrant)

then

y = (1/2)^3 + k

y = 1/8 + k and y = 3x/4

so

3 x/4 = 1/8 + k

but x = 1/2

3/8 = 1/8 + k

k = 2/8 = 1/4
