If a Lineweaver-Burk Plot Gave a Line with an Equation

If a Lineweaver-Burk plot gave a line with an equation of y = 0.490 x + 0.059, what is the velocity at a substrate concentration of 5 mM? The original units for substrate were in mM and velocity in mM/s.

A) 0.288 mM/s
B) 0.399 mM/s
C) 2.51 mM/s
D) 6.37 mM/s
E) the velocity cannot be determined from these data
