Question

1.dilate by 3/5 : (20,10)

2.translate (x+5,y-6): (7.8)
3.reflx across th x-axis: (4,7)
4.rotate 270 degrees: (7,9)

Answer 1

a) )12,6)

b) (12,2)

c) (4,-7)

d) (9,-7)

Explanation:

a) Dilation

When we dilate, we multiply the given scale factor by each of the coordinates

We have this as follows;

(20 * 3/5, 10 * 3/5) = (12, 6)

2. Here, we will add 5 to the x-axis value and subtract 6 from the y-axis value

We have this as;

(7+ 5, 8-6) = (12,2)

3. By reflecting across the x-axis

we have (x,y) changing to (x,-y)

so we have ;

(4,7) becomes (4,-7)

4. Rotation by 270 degrees (7,9)

If clockwise;

(x,y) becomes (y,-x)

so we have

(7,9) becoming (9,-7)
