Given that the slope of a line is 2/3, that passes through the point (4, -1), i.e


\begin{gathered} m=(2)/(3) \\ (x_1,y_1)\Rightarrow(4,-1) \end{gathered}

The formula to find the equation of straight line is


\begin{gathered} y-y_1=m(x-x_1) \\ \text{Where m is the slope of the line} \end{gathered}

Substitute the values into the formula of the equation of a straight line


y-(-1)=(2)/(3)(x-4)

Solve for y i.e make y the subject


\begin{gathered} y-(-1)=(2)/(3)(x-4) \\ y+1=(2)/(3)(x-4) \\ \text{Open the bracket} \\ y+1=(2)/(3)x-(2)/(3)(4) \\ y+1=(2)/(3)x-(8)/(3) \\ y=(2)/(3)x-(8)/(3)-1 \\ y=(2)/(3)x-((8)/(3)+1) \\ y=(2)/(3)x-((8+3)/(3)) \\ y=(2)/(3)x-(11)/(3) \end{gathered}

Thus, the answer is


y=(2)/(3)x-(11)/(3)

Thus, the answer is the last option.
