Question

2. suppose a point at (2,3) is translated to (7,-1). which rule
describes this translation?
a) translate right 5, down 4
b) translate left 5, up 4
c) translate right 9, down 2
d) translate left 9, up 2

3. if the point (-5, -8) is reflected over the y-axis, what are the coordinates of the reflected point?
a) (5,8) b) (-5,8)
c) (5, -8) d) (-8, -5)

my answers 2. d 3. b

Please, please, please, please, please help me!!!! thank you if you do, if you don't oh well to me......thank you :)

Answer 1

2.

x = 2
y = 3

translated to ( 7 , - 1 )

7 - 2 = 5

- 1 - 3 = - 4

a) translate right 5 , down 4


3.

x = - 5

y = - 8

When you reflect a point across the y-axis, the y-coordinate remains the same,
but the x-coordinate is transformed into its opposite.


c ) ( 5 , -8 )
