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.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
