Use the points H(−4, 1) and K(4, 1).
(a) From two points , we will get a vertical line when 'x' values are same and horizontal line segment when 'y' values are same
Here in H(−4, 1) and K(4, 1) , the y values are same so the segment HK is a horizontal . The length is the difference between x values ( 4 -(-4)) = 8
Segment HK is a Horizontal segment that is
8 units long.
(b) Describe the image of segment HK under the transformation
(x, y) -----> (−y, x)
H(−4, 1) -----> (-1, -4)
and K(4, 1) ---> (-1, 4)
'x' values are same so line HK is Vertical. The length is the difference between y values ( 4 -(-4)) = 8
The image of segment HK is a Vertical segment that is
8 units long.
(c) escribe the image of segment HK under the transformation
(x, y) ----> (2x, y)
H(−4, 1) -----> (-8, 1)
and K(4, 1) ---> (8, 1)
'y' values are same so line HK is Horizontal. The length is the difference between y values ( 8 -(-8)) = 16
The image of segment HK is a Horizontal segment that is
16 units long.

I is the square root of negative one
Cost of a hat bought by Marcel = 
Cost of a pair of socks = 
Cost of 2 pair of socks =
= 
Total price of hat and two pair of socks = 
A sales tax of 
on this purchase = 
=
= 
2.25
Therefore, the total price including the sales tax = 
=
A) angle A is equal to angle Z
angle B is equal to angle X
angle C is equal to angle Y
b) angle(s) AB are equal to ZX
angle(s) AC are equal to ZY
angle(s) BC are equal to XY
c) triangle BCA is equal to triangle XYZ
