Which equation represents a line that passes through (2, -1/2) and has a slope of 3? y-2 = 3(x + 1/2)
y-3 = 2(x + 1/2)
y+1/2= 3(x - 2)
y + 1/2 = 2(x – 3)

y+1/2= 3(x - 2)

Step-by-step explanation:

The slope can be seen to be 3 by factoring out each of the right sides.  Only a and c have a slope of 3.  Next if the point (2,-1/2) is plugged into the equation of c then you get an answer of 0=0.  Beacuse both sides are equal when the point desired is plugged in it is the correct answer.
