Which statement about the line 4x+y = -24 is true?

Answer:
B. (-6, 0) is on the line
Step-by-step explanation:
The points of concern are those where y=0. Using that in the equation, we find the x-value to be ...
4x +0 = -24
x = -24/4 = -6
That is, the point (-6, 0) is on the line and is a solution to the equation.

Additional comment
Answer choices C and D can be rejected immediately, because they are nonsense. If a point is on the line, it IS a solution. It will not be on the line if it is not a solution.
