Line segment ab has endpoints A(-4, -10) and B(-11, -7). To find the x-coordinate of the point that divides the directed line segment in a ratio, the formula x=(a/a+b)(x2-x1)+x1 was used to find that x=(3/3+4)(-11-(4))+(-4)

What is the x-coordinate of the point that divides ab into a 3:4 ratio?

answer choices:
