There are many different ways of representing the equation of a line. With the given information, the best form of the equation to use is point-slope form which can be written as \(y-y_{1}=m(x-x_{1})\) where \((x_{1},y_{1})\) is the x and y coordinates of a given point on the line and \(m\) is the slope of the line. Since you are given that the slope of the line is 3 and has the point (-1,-8), the equation should look like \(y+8=3(x+1)\), which is letter choice D.
