Question

15 POINTS

Points A (-10,-6) and B (6,2) are the endpoints of AB.
What are the coordinates of point C on AB such that AC is 3/4 the length of AB?

*(0,-1)
*(2,0)
*(-2,-2)
*(4,1)

Answer 1

First you need to find the distance formula for AB by using the distance formula.  D= sqrt root of (y2-y1)^2+(x2-x1)^2  The points are A (-10,-6)  B (6,2)  D= sqrt root ( 2--6)^2+(6--10)^2  D=sqrt root 64+256  D=sqrt root 320
