Answer:

Step-by-step explanation:

Let the equation of the line is y = mx + c

where m = slope = 3

and c = y-intercept

Now the equation of this line will become

y = 3x + c

Since this line passes through (2, [tex]\frac{-1}{2}[/tex])

so  [tex]\frac{-1}{2}[/tex] = 6 + c

c =  [tex]\frac{-1}{2}[/tex] - 6

  =  [tex]\frac{-13}{2}[/tex]

So the line will be y = 3x + [tex]\frac{13}{2}[/tex]
