Answer: option D.
Step-by-step explanation:
The equation of the line is slope-intercept form is:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept.
Then, you can solve for y to see the y-intercept, as following:
[tex]5y=-2x-30\\y=-\frac{2}{5}x-6[/tex]
Therefore, the b is:
b=-6
The answer is the option D.
