Which equation represents a line that passes through (2, -1/2) and has a slope of 3?
uranmaximum [27]

Answer: y= 3x -  6\frac{1}{2}

Step-by-step explanation:

Since we know the slope and a set of coordinates we can insert them into the formula y=mx+b and find what b is.

y=mx+b

-1/2=3(2)+b

-1/2=6+b

-1/2-6=6-6+b

-6 1/2=b

Therefore the equation is y=3x -  6\frac{1}{2}
