SOLUTION
From the question, the equation of the line is given as
[tex]\begin{gathered} y=-3x-8 \\ comparing\text{ this to the equation of line in slope-intercept form, we have } \\ y=mx+b,\text{ where m is slope and b is y-intercept} \end{gathered}[/tex]
So this means that the slope of this line m is -3.
A line that is parallel to this line will also have a slope of -3
So, looking at the 3rd option
[tex]\begin{gathered} y=-3x+7 \\ it\text{ has a slope of -3} \end{gathered}[/tex]
Hence the answer is
y = -3x + 7, the 3rd option
