21. Given directed line segment WV , find the coordinates of R such that the ratio of WR to RV is 3:4. Plot point R.

Step-by-step explanation:

Let the coordinate of the points W, V and R are and respectively.

The coordinate of the section point, which divides the line joining the two points and in the ration is

and

.

The given ration is,

.

The exact point can be determined by putting the value of the exact coordinate in the above-obtained formula.

i think it is x = 1.2
