Point A(7,9) is dilated from the origin by scale factor r=6. What are the coordinates of point A'?

(42, 54)

Step-by-step explanation:

Coordinate rule for a dilation with scale factor k is simply this: (x, y) --> (kx, ky).

Multiply both coordinates by the scale factor given(r)

1 1/4 hours

step-by-step explanation:

2/4 + 2/4 + 1/4 = 5/4 or 1 1/4

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
