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:
-7
-5
-3
-1

-7

Step-by-step explanation:

Here we want to find the point that divide the segment AB into ratio 3:4.

The coordinates of A are

A (-4, -10)

B (-11, -7)

We can use the formula

In order to find the x-coordinate of the point that divides AB into a 3:4 ratio.

In this problem, we have:

a = 3

b = 4

where a/b = 3/4 is the ratio, and

Are the coordinates of the endpoints

Substituting into the formula, we find

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16
