Answer:
The location of the point that is 3/4 the distance from
is
.
Step-by-step explanation:
Let
and
the endpoints of the segment, we can determine the location of the point that is 3/4 the distance from
by the following vector equation:
(1)
If we know that
and
, the location of
is:
![C(x,y) = (-6,-16)+\frac{3}{4}\cdot [(34,2)-(-6,-16)]](https://tex.z-dn.net/?f=C%28x%2Cy%29%20%3D%20%28-6%2C-16%29%2B%5Cfrac%7B3%7D%7B4%7D%5Ccdot%20%5B%2834%2C2%29-%28-6%2C-16%29%5D)
![C(x,y) = (-6,-16)+\frac{3}{4}\cdot (40,18)](https://tex.z-dn.net/?f=C%28x%2Cy%29%20%3D%20%28-6%2C-16%29%2B%5Cfrac%7B3%7D%7B4%7D%5Ccdot%20%2840%2C18%29)
![C(x,y) = (24, -2.5)](https://tex.z-dn.net/?f=C%28x%2Cy%29%20%3D%20%2824%2C%20-2.5%29)
The location of the point that is 3/4 the distance from
is
.
Answer:
m = 1/3, b = 2
Step-by-step explanation:
The equation is already written is slope-intercept form, y = m x + b.
