Problem

The equation of a line is y=32x−4y = \dfrac{3}{2}x - 4. Which one of the following point–slope equations represents the same line? (a) y+4=32(x−0)y + 4 = \dfrac{3}{2}(x - 0) (b) y−4=32(x−0)y - 4 = \dfrac{3}{2}(x - 0) (c) y+4=23(x−0)y + 4 = \dfrac{2}{3}(x - 0) (d) y+4=−32(x−0)y + 4 = -\dfrac{3}{2}(x - 0)
