For the line segment whose endpoints are A (0,0) and B (4,3), find the X value for the point located 2/3 the distance from A to B. A) 2.2 B) 2.7 C) 3.3 D) 3.5

First, find the number you add to the x value of A to get to the x value of B can you do that ?

I don't know how...thats why I asked.

in A(0,0) which number is the x value ?

and in B, it's 4

OpenStudy (phi):

yes, you can't go wrong on that one. and 4 for B now how much do you add to 0 to get to 4 ?

OpenStudy (phi):

do you see that must be 4? 0+4= 4 find the X value for the point located 2/3 the distance from A to B. means find ⅔ of 4

can you find ⅔ of 4 ? i.e. ⅔ * 4

8/3

OpenStudy (phi):

yes. change that to a decimal and round to the nearest tenth. (because your answers are in that form)

2.7? is my answer right

You first line up your coordinates and subtract. You get 4 for x and 3 for y. Then put 4 as a fraction (4/1) and multiply it by 2/3 to get 8/3 or 2 and 2/3. Next put 3 in a fraction (3/1) and multiply it by 2/3 to get 2. Add 2 and 2/3 to the original x coordinate (0) to get 2 and 2/3. Next add 2 to the original y coordinate (0) to get 2. Your answer is (2.67,2).
