Chapter 4, Problem 10RP

(a)

To determine

To calculate: Coordinates Of B

Answer to Problem 10RP

(-1, 4)

Explanation of Solution

Given information: Coordinates of A are (1,4)

Calculation:

When A is reflected about the Y axis, its X coordinates change sign, hence of B are (1, 4)

(b)

To determine

To calculate: Coordinates Of C

Answer to Problem 10RP

(4,-1)

Explanation of Solution

Given information: Coordinates of A are (1, 4)

Calculation:

Rotation of A with respected to origin, ${90}^{\circ }$ clockwise results in C (4,-1).

(c)

To determine

To calculate: Coordinates Of D.

Answer to Problem 10RP

(8, 6)

Explanation of Solution

Given information: Coordinates of A are (1, 4)

Calculation:

X Coordinate will be recreated by 7 units and Y coordinates will be recreated by 2 units, hence D (8, 6)
