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.

The equation of the line has the form: y = ax+b parallel to the line y = -2x + 7
=> a= -2
Passes through (4,1) => x=4, y=1
Substituting into the equation:
1= -2x(4) + b => b= 9
=> y= -2x + 9
