Answer:
Given:
1st point (5,8)
2nd point (7,10)
3rd point (9,12)
4th point (11,14)
After transformation, the sing of the x-coordinate for each ordered pair has changed. From positive, it becomes negative. However, the sign of the y-coordinate is assumed to retains its original sign.
From positive x and positive y to negative x and positive y, this is C. REFLECTION ACROSS THE Y-AXIS.
Step-by-step explanation:
Answer:
(x,y) → (ax,ay) .
Step-by-step explanation:
A dilation is a transformation that changes the size of the image. It either shrink or enlarge a shape by using a scale factor about a center of dilation.
If we transform point (x,y) by using dilation with scale factor k (assume center of dilation at (0,0) then the coordinate of the image will be (kx,ky).
So, the coordinate expression represents the coordinates of any point after dilation by a scale factor of a:
(x,y) → (ax,ay) .
Answer:
x+1
Step-by-step explanation:
all sequences are added by one, so x+1
Answer:
(a) HI
(b) GJ
(c) KL
(d) 2 units
Step-by-step explanation:
For d, I divided 4 by 2 because a radius is half of the diameter
