Answer:

WO
√(13)\ \ \ (3)/(2)

OR
√(13)\ \ \ - (3)/(2)

RM
√(13)\ \ \ (3)/(2)

MW
√(13)\ \ \ - (3)/(2)

Explanation:

One has to find the slope, and the distance between the successive points on the plane. Use the slope and distance formula to achieve this.

Slope formula:


(y_2-y_1)/(x_2-x_1)

Distance formula:


√((x_1-x_2)^2+(y_1-y_2)^2)

Remember, the general format for the coordinates of a point on a Cartesian coordinate plane is the following:


(x,y)

1. WO

Coordinates of point (W): (3, -5)

Coordinates of point (O): (6, -3)

Find the slope:


(y_2-y_1)/(x_2-x_1)


((-5)-(-3))/((3)-(6))=(-5+3)/(3-6)=(-2)/(-3)=(2)/(3)

Find the distance:


√(((-5)-(-3))^2+((3)-(6))^2)


√((-2)^2+(-3)^2)\\=√(4+9)\\=√(13)\\

2. OR

Coordinates of point (O): (6, -3)

Coordinates of point (R): (4, 0)

Find the slope:


(y_2-y_1)/(x_2-x_1)\\=((0)-(-3))/((4)-(6))=(3)/(-2)=-(3)/(2)

Find the distance:


√((x_2-x_1)^2+(y_2-y_1)^2)


√(((0)-(-3))^2+((4)-(6))^2)=√((3)^2+(2)^2)=√(9+4)=√(13)

3. RM

Coordinates of point (R): (4, 0)

Coordinates of point (M): (1, -2)

Find the slope:


(y_2-y_1)/(x_2-x_1)\\=((0)-(-2))/((4)-(1))=(2)/(3)

Find the distance:


√((x_2-x_1)^2+(y_2-y_1)^2)


√(((-2)-(0))^2+((1)-(4))^2)=√((-2)^2+(-3)^2)=√(4+9)=√(13)

4. MW

Coordinates of point (M): (1, -2)

Coordinates of point (W): (3, -5)

Find the slope:


(y_2-y_1)/(x_2-x_1)


=((-5)-(-2))/((3)-(1))=(-3)/(2)=-(3)/(2)

Find the distance:


√((x_2-x_1)^2+(y_2-y_1)^2)


=√(((3)-(1))^2+((-5)-(-2))^2)=√((2)^2+(3)^2)=√(4+9)=√(13)
