B. Y-3=2(x+1/2)
C. Y+1/2=3(x-2)
D. Y+1/2=2(x-3)

C.

Step-by-step explanation:

Given

Required

Equation of line

Let m represents the slope of the line;

m is calculated as thus

By substituting the right values in the formula above;

becomes

Multiply both sides by

Reorder

Hence, the equation that represents the line is
