Answer:
B. 5x + 3y = 0
Explanation:
Parallel lines have the same slope.
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
The formula of a slope:

We have the points A(-3, 0) and B(-6, 5). Substitute:

The line passes through the origin, therefore the y-intercept is equal to 0.
Therefore we have the equation:

Convert to the standard form

multiply both sides by 3
add 5x to both sides
