Which describes the transformations of y =fx) that would result in the graph of y =f-x) -7. a reflection in the y-axis followed by a translation down by 7 units
a reflection in the y-axis followed by a translation up by 7 units
a reflection in the x-axis followed by a translation down by 7 units
a reflection in the x-axis followed by a translation up by 7 units

the answer is mc^1-1jpeg

the image of (6, 9) under a dilation is (4, 6). the scale factor is

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)
